Epic Run: Keystone Standard Basin

By: Magi Scallion

I got to spend a very lovely weekend in Revelstoke, BC, this fine September. Revelstoke has long been a winter destination for skiers and snowmobilers with legendary back country and deep powder, but it’s now becoming a mountain bike and trail running destination in the summer months.

A lot of the recent summer hype has been around two amazing, epic trails that were recently build or rediscovered. The Frisbey Ridge trail runs through the Monashee mountains, on the west side of the famous Columbia River, and is a panoramic 26 km out-and-back run. The trail was recently refurbished and gives the feel of front-country trail running: limited rocks and routes with great panoramic vistas. The trail involves 7 km of climbing right out of the parking lot (which means 7 km of descending back to the parking lot) so put on your best suffer smile and get to it: it’s worth it. I, personally, did not do this run, but got the report from a few friends who did it the day before I arrived.

The trail I got to enjoy was Keystone Standard Basin, which falls on the east side of the Columbia River, on the edge of the majestic Selkirk Mountains. This trail, similar to Frisbey is about 45 minutes of driving from the Town of Revelstoke. Don’t complain about the drive because it takes you several hundred feet above the valley floor (which means less self-propelled climbing).

To be perfectly honest, I enjoyed the Keystone trail as a cyclist, not a runner. I did the Terry Fox Run in the morning (a hard 10 km effort with a bunch of young guys) so was feeling the need for some seated afternoon exercise. There were plenty of runners on the trail, though, so I can assure you that it is spectacular no matter what form of exercise you choose.

The trail head has lots of parking and also an outhouse: a great feature considering it’s a 45 minute drive from town! I was warned that the first 25 minutes of the trail was all climbing… hard climbing. I was exhausted from the race in the morning so was not really looking forward to this. Let me tell you how happy I was to crest the worst part of the climb within 10 minutes. I am not superwoman: it’s really not that bad. You do continue to climb for about 30 minutes but it’s more of a benched climb with some flatter rest sections. Not as bad as you think!

Once you get the climb over with, you enter into some sublime alpine meadows, which sums up the rest of the trail. It’s 11 km to a lake and small cabin, along a trail that runs around a spectacular basin. The views to the Monashee mountains and deeper into the Selkirks are amazing. Take a camera because you cannot take a bad picture of this area! Rumour has it that the flowers are waist high in the mid to late summer months: that must make for some beautiful colours!

There are lots of viewpoints and features along the way, including a few small streams. You can bring your dog along (best to have a well trained or on-leash dog, in case you encounter some animals). The trail was designed for hiking but the bulk of users are now mountain bikers and trail runners, who have a very symbiotic relationship.

There are lots of great places to stay and eat in Revelstoke – it’s a cute mountain town – so make a weekend of it! I highly recommend:

Camping: Williamson Lake Campground (A lake for swimming and decent tent sites)
Coffee: La Baguette (also a great place for cheese… mmmm cheese)
Greasy Spoon Breakfast: The Frontier Restaurant (who doesn’t love recovery food?)
Wine: Benoit’s Wine Bar (Good wine selection and food)
Beer and Burgers: The Village Idiot (It’s got character and beer…)

Hey Guys, you’ve been “Chicked” !!!

It’s inevitable, some day it’s bound to happen. You might have a mental lapse of judgement during a race, or might not have trained up to your potential. You might (like me) just be getting older, slower, less focused on “the time” and more focused on “the finish”.  We all as runners want to do our personal best, we all want to set goals, train for, and then meet them.

This preamble leads me to a very cute story and an awakening of sorts…let me explain…

While running the Creemore Vertical Challenge 25k trial run this past year, I heard for the first time the term “Chicked”.  Now, this is a term used to describe “the act of getting passed by a stronger runner, who just also happens to be a woman”.  In this specific case, I was passed by my buddy’s girlfriend ( who in my defense is half my age, and runs like a gazelle ).   Let’s call her “Catherine”…and yes, that is her real name.

Now Catherine had never run this race before and I give her all kinds of props for running on that specific day as the course was very muddy and technical…lots of steep single track, mostly up hill…some back roads and open fields…a small creek,  in fact, if truth be told, she almost backed out of the race because the footing on the course when it is in perfect condition is a bit iffy, and it had poured rain an hour before the race, making the single track a slippery, muddy, mess.

I was feeling pretty good that day, I had a really good run, and in fact, had shaved about 14min. off my best time, running this race three times before.  Having said that…here’s what happened.

So when my buddy, “Conar”… yes that’s his real name…so when I came up to the 21k aid station, Conar was volunteering at this station.  I had asked Conar how Catherine was doing…his response was “ya, she’s already through, you’ve been “Chicked” by her, I laughed an awkward laugh and trying to stay positive, I said, “good on her” and continued to run the final 4k of the race…  I was really OK with it…honest, and let me tell you why.

There are some awesome runners out there who I marvel at …both male and female.  The runners who run so fast that by the time I am half way through a marathon, they are finishing, doing a victory lap, and enjoying the spoils of being first at the food table.

I know I am never going to be that fast…truth be told, the average male runner has been “Chicked” every race they have ever run unless they are at the front of the pack.

So take from this blog a lesson on both humility and reality…and I say “Bravo Ladies…Bravo”.

Army Run: How Do I Know I’m Ready?

G’Day Everyone!

 

I’m extremely excited for the Army Run, it’s almost arrived!

As much as I enjoy running, I’ve loved my last week tapering and stepping off training for a little while to allow my legs to rest up.  The Army Run (based in downtown Ottawa) is a run that I’ve been wanting to do for about about 2 years now. It’s become really popular- this year it sold out early and I was fortunate enough to find an entry from someone on KiJiJi.  I’ve been inspired by the countless stories and comebacks. Not to mention the route is really visual, but how do I know I’m ready?

There’s nothing worse than running without confidence. It’s debilitating mentally to get out there and have too many questions before a race and feel really uncertain of how things will go. This usually ends up creating a lot of apprehensions come race time. More often than not, it’s a scenario that will likely end up to be painful. Obviously it’s ideal to show up on race day feeling nervous and excited, but it’s really great to know you’ve had a few runs with “the groove”; it’s that synergy of legs, mind and solid training, the point on a tempo run when you feel invincible. Whether it’s the song you’re listening to, food you ate, sleep you got, or the weather outside, this is a great feeling that every runner should get to enjoy while training. It’s especially a nice feeling before a race to provide you with a burst of confidence and positivity.

Usually during the grind of training, I can always hit “the groove.” This past couple of months though, I’ve had to go searching for it. As much as I wanted to enjoy that quick pace and thrive in it, I ended up struggling. I decided a few days rest would be beneficial for my mind and legs. For me that’s exactly what I needed and I’ve run in “the groove” a few times now. Where everything clicks and race pace is locked in, only up until now have I felt race ready. It’s my little victory as a security before race day.

You’ve got to love a sport where anything can go wrong on the big day, anything from: Nutrition, equipment, fatigue, injury, weather,health, etc. etc. Call it what you will: “the groove”, “synergy”,”clicking.” Once you get there, you’ll know what I mean, it’s awesome, and it’s just another reason to keep lacing up those kicks!

For those of you also taking part in a race this weekend – have fun!! You’ve done the training, now is time to let loose.

Here’s to you and Happy Groovin’

Strong Finish! (On the right)

 

Let’s fartlek! (seriously, it’s a running thing)

In my efforts to spice up my running routine I’ve left my options open. I’m trying to not get caught up in the scheduling of running and try to enjoy the actual run itself.

This summer my kids took swimming lessons at the local pool. This left me about a ½ hour to myself in the evenings. This is better than most nights. I take what I can get. With the idea of running both kid, and guilt-free, I prepared to run as soon as they hit the water.

The problem without planning the run is that I start most runs walking and talking to myself. Which direction to go? How fast? How far? I threw caution to the wind and just went with it. While I was just ‘going with it’ I realized that this was the perfect opportunity for a fartlek run.

Honestly, I’ve never purposely did a fartlek session. I think it’s the word itself I don’t like. I never want to have to come home from a run and tell my husband that I had a great fartlek. He’s not a runner…he just wouldn’t get it.  Besides, I usually have pacing issues anyway and my speed tends to waver throughout my runs on their own.

I had the perfect opportunity for a little fartlek, so I took it. It’s no wonder the word comes from the term ‘speed play’. It is like playing; making the run fun and interesting. I spent most of the time wondering why I’ve never really done it before.

I sped up when I wanted, slowed when I wanted. I hopped, skipped and jumped (that counts, right?) my way through town. With my swimming lesson time limit, I managed to get in a fun, sometimes intense, run. It was just enough of a workout to keep me motivated.

So…do you fartlek? Or does that word make you giggle like a 5th grader?

Mirror, Mirror (mirror, mirror, mirror) on the wall

This week I went to the mall. Typically this isn’t a noteworthy event unless I find a great sale or have a particularly awesome Orange Julius. This trip was memorable for all the wrong reasons. The problem started when I entered the dressing room, an annex of judgement and humiliation which no woman should have to endure for at least six months postpartum (a full year is better).

Shopping for running apparel is especially problematic. Technical material, while wonderful for keeping sweat away from delicate areas never meant to fester in pools of bodily fluid, tends to emphasize every lump, bump and wobble (Side note: Doesn’t Lump, Bump & Wobble sound like the name of a great kid’s musical group?). So I knew what I was getting myself into, however as I’m still nursing my five month old, I’ve discovered my pre-baby running bras aren’t necessarily as efficient as I need them to be (imagine trying to stuff a quarter-pound hotdog into a breakfast sausage casing). If I was going to find a new one in time to test it out before my half-marathon in just over two weeks, the time had to be now.

I selected a few options, squeezed the stroller into a dressing room and began trying them on. No sooner did I have the first one on, Little Dude began to cry. Not a little whimper that slowly escalates, but rather the type of immediate, ear-shattering wail that sends passers-by scrambling for their phones to speed dial Family Services. I tried everything: a soother, rocking the stroller, covering him with my coat, outright pleading and singing a verse of Bohemian Rhapsody, but his complaint only intensified. I knew what had to be done and I had two options: get dressed, put the clothing on hold, leave and come back later, or just feed him there. I had the room and I was already topless. The math was pretty simple.

Fortunately the dressing room had a small stool so I was able sit down. Fortunately so I thought in the moment. The room also happened to come equipped with a three-way mirror on one wall, and a big, full-size mirror covering the opposite wall. I know the implications. The makers of spandex products want you to think long and hard before you dare venture out in public wearing their clothing so they make sure you can verify at every angle that this is, in fact, an appropriate purchase. Not-so fortunately, this meant that while breastfeeding, I had views multiplied as far as the eye could see and several minutes of unobstructed time with which to scrutinize myself.

Normally when I see so much skin revealed in a mirror, I’ve just gotten out of the shower and I’m standing upright and sucking things in. I’m also near the end of training for my half-marathon. Such factors had mistakenly led me to believe I wasn’t doing too badly in the post-baby body department. Fortunately, when you’re willing to pay $92 for a pair of workout pants, you get a free reality check included with purchase.

I’m still carrying an extra 10 to 15 pounds of weight I didn’t have last year during the same race, a fact that hasn’t escaped me. And while I try to remind myself that it could be much, much worse, every article I’ve ever read explaining how each extra pound of weight contributes to slower running times continues to echo in my head. I will spend the next two weeks leading up to the race reminding myself that I should be grateful to just finish the distance rather than convince myself a new PR is necessary when I’m not necessarily in top physical form. I’m still healthy, strong and hopefully ready to achieve a goal I set barely after the second pink line appeared in the test window.

Back in the dressing room, I wrapped up the feeding ten minutes later, looked down at the face of my now-peaceful son, said a silent prayer of thanks for a healthy child, proceeded to find what I originally came searching for, and vowed to start a letter-writing campaign lobbying retail locations to include at least one dressing room equipped with  shoulders-up only mirrors.

Punishment and Vindication

The last drink I had was on January 14 2010 and if I am being completely transparent (and why not be honest, the cat’s outta the bag) it was more like 18 drinks…near as I could count.  I had a farewell party to myself.

The next day and the days and weeks that followed were filled with discomforts that I never want to relive and that I never want to forget. Forgetting would be disrespectful. Detoxing was hard on my mind and my body. I am afraid if I minimize the torment I felt, I risk pouring that first drink that will send me spiralling back into the world of lager and ale.

So, I remember, I respect and I run. It has been working.

When I run, it’s usually full speed ahead, just shy of what should be a 5 or 10k race pace. I like the punishment; it keeps me in the moment, so I won’t forget how far I have come. My mind understands that running so hard, so often is one of the reasons that I go from one injury to the next, but the part of me that needs punishment goes out too fast every time no matter  what common sense would dictate.

Another part of me craves performance success, and that’s why I push so hard. It’s as if constant improvement, seen by posting decent and faster times might prove that I am good at something other than emptying wine bottles. I need to prove that I can still do something with the bit of running talent I had at one time. I am driven to prove that I can do more with running than just “running” a tab. I have squandered much time, money and talent and none of it can be retrieved but the time, money and talent I have left are going to be spent on running harder, faster and longer.

So from where I stand in these running shoes, punishment and vindication through pounding the pavement are what keep me on the straight and narrow.

You might be a runner…

Let’s face it, we runners are a “strange breed”. Now keep in mind that when I use the word “strange”, I do so with the best of intentions…strange is good, so let’s just embrace our strangeness an move forward. We do things that on the outside appear to be “a little different”, or as my non-running friends are oh so quick to point out… “just plain crazy” !

So, for no other reason to salute runners of all levels, and in the tradition of Grammy award winning comedian Jeff Foxworthy, here is my version of

“ You might be a runner ”

If you have ever driven 5 hours, for the privilege of running for 4 hours…

If you pay more than $ 5.00 for a pair of socks…

If you “love the sound of Cow Bell in the morning”…

If you have found a way to take “Manscaping” to a whole new level…

If you know what Body Glide is, and have applied it to parts of your body  too personal to mention in an iRun blog…

If your idea of “PB” does not include jam…

If you have ever gone up or down a flight of stairs backward out of necessity…

If you are the owner of a “utility belt” but are not in the “crime fighting” business…

If RICE is something you do, as well as something that makes a tasty side dish…

If you have ever applied bandages to your nipples…

If you have ever paid the price as a result of forgetting to apply bandages to your nipples…

If you find “black and blue” toenails in any way sexy…

If you are not prone to giggle when someone yells the word “FARTLEK”…

If you have ever uttered the words “my new watch is GPS enabled”…

If “tens and ones” means more to you than “change for a twenty”…

If you have ever asked a salesperson “how well does this garment wick away moisture”…

and finally…

If you have ever proclaimed “ I am never running this distance ever again ” while in the middle of a subsequent race of the aforementioned distance…you just might be a runner.

Being the fastest doesn’t mean you will win

Ed McNeely – Peak Centre for Human Performance

Physiologically running success is depends on VO2 max, lactate threshold and running economy. Most recreational racers and even sub elite competitive runners pay little attention to the other little things that can make or break a race. One of these factors is positioning and the line that you choose to run. We can learn an interesting lesson about this from the 800m and 5000m Olympic finals in Sydney in 2000. In a paper published in the British Journal of Sports Medicine Jones and Whip analyzed the paths run by the participants in these races.

The 800m race was won by Schumann in a time of 1:45.08, the second place finisher Kipketer finished in 1:45.14, making it a really tight race. During the race Shumann race as close to the cur as possible throughout the race and covered a total of 802m while Kipketer tried to stay out of the crowd and ran in lanes 2 and 3 for much of the race and covered 813m. Kipketer ran the race with an average velocity that was 0.1 m/s faster than the winner Schumann. If they had both covered exactly 800m Kipketer would have won gold by 1.36 seconds instead of finishing second.

In the 5000m final Wolde of Ethiopia won the race in a time of 13:35.49 covering a total of 5022m. The second place finisher Saidi-Sief of Algeria finished in a time of 13:36.20 covering a distance of 5028m. Saidi- Sief would have run the race in 13:31.65 compared to 13:31.91 for Wolde had they both covered exactly 5000m.

It should be clear from these two examples that the line you choose can have an impact on your performance and the outcome of a race. While you may not be doing your running on a track on race day taking the shortest route possible will be your best path to a personal best. Running a bad race line could also mean that you miss a personal best even though you worked your butt off and made big improvements in your fitness. If the race is local do a few of your training runs on the course so that you know where corners and curves are and how you can cut them as close as possible to improve your line. There are GPS systems available now that will help you track your path and let you compare it to an optimal path. If the race is not local try to walk or ride the course at least once before you race it and spend some time with course maps to figure out your best line. It may not sound like a big thing but why run any further than you have to in a race.

I figured it out… what running was becoming for me.

The previous year-ish (2009) was spent padding my ego with over achievements for a guy who never ran a day in his life before. What I didn’t expect was that my own body would be the thing that humbled me.

Since that time I have said that running is the most honest thing you can do. In running, you can’t say you can do more than you do. Well actually, you can say you can do more, but as soon as you ‘toe the line’ you will be exposed as a fraud.

For the longest time I was even backing up what I said I could do (but shouldn’t be), but my body slowly started to break on me. It started to expose me and it was pretty demoralizing. It was an internal battle pitting my mind against my body. I never told anyone about my injured feet. I hated the idea of having to scale back my running, or to change anything about my progression. My plantar fasciitis was crippling me and I was ignoring it.

Ok. so. How did I figure it out (again as usual, ignoring the injury)?

Well, as I was on my recovery hiatus, I surprised myself as I realized I loved running . Now I was starting to feel like I loved to run. I think there is a difference, between loving running (the overall idea) and loving to run (the physical act). I think loving to run is to love the act of it. I mean, each step of it. The hard ones, the euphoric ones, the beginning, the end, with friends and alone, I realized I enjoyed all of steps in running. It’s really hard to articulate after this much time, but I remember the feeling clearly the first time I was in the middle of a really hard part of a run, and found myself appreciating it, and just accepting the pain and suffering as just what it was, and that I made this choice to be here, and it is what it needs to be at this moment.

I read a book called ‘Zen and the Art of Running’. It showed me that while running I could be ‘in’ the present. To enable my mind to appreciate this moment, my surrounding and the feeling I was having at that second. And that I could do that with each step. At first it was hard to stop looking at the distance ahead. My mind would wander to a moment in the future where the run might be harder. like a hill, or the last couple kms of a 20k training run. This kind of thinking would take me away from the appreciation of the moment. That I was accomplishing something right now.

I ran the Harvest Half at the beginning of October. It was amazing. It was the polar opposite of the Calgary Half 6 months earlier. I didn’t feel any internal pressure to be this epic running machine, in fact I didn’t even tell anyone that I was running it (much). For the Calgary Half I was looking for faces in the crowd, looking for a triumphant finishline, looking for external approval. This time I just got up, drove to the race, ran it, had a coffee with friends, then came home. This is what I wrote in my blog at the time:

I had fun… can you believe it? After the tough experience in the first one.. who’d know that I would actually have fun at this one?

It’s all about the attitude. I will never be an elite runner, and my personal records will come and go with time I am sure. So now that I have a few races under my belt, I felt like I could go out there and take it all in, watch the race from the race itself, so to speak. I did that and had a hoot! Don’t get me wrong, it is still a struggle to run 21.1kms, it’s just that I knew I could do the distance, have trained for it, and just knew what to expect I guess.

CIMG0041

I can tell from my writing that I still didn’t completely get it at the time, but I was on the right track.

BUT: I was still injured. My feet were still a mess. I still hadn’t told anyone. I was too proud I guess.

After the race I made up my mind to go back to run club AND I would volunteer as a pacer for a 1/2 marathon clinic. This decision proved to be one of the best things I could have done. What came out of this, and what I’ll discuss in future blogs is:

  • I loved to give back to running
  • my best friends are runners
  • There was a solution to my foot problems
  • regardless of my less than ideal fitness situation, running is always there, waiting next to my shoes at the door.
  • Barefoot running is actually a thing, that people do. hmmmm.
  • The book ‘Born to Run’
  • Blogging about running would introduce me to some of the coolest people in the running world
  • Runners love running photos.

Thank you so much for reading. I won’t go too deep into all the gory details of the past because I want to chat with you about what’s going on right now in my running. There are a few more things to write about that make up the basis for my current running life (and life in general).  I am on twitter here. Facebook here.

CARBO LOAD!!!

For many athletes, “carb-loading” is a pre-race ritual. And with good reason: carbohydrate is an important fuel for exercise, whether you’re running for a personal best or to complete a particular distance. But before you put on your extra-loose pants and head for the nearest all-you-can-eat pasta bar, let’s ask a few questions.

What is carb-loading and why is it done?

Your body uses carbohydrate and fat to perform exercise. Even a very lean athlete has a virtually unlimited supply of stored fat for exercise, but a very small supply of carbohydrate (stored as glycogen in the muscle and liver). During exercise, the faster you want to go, the more carbohydrate you will require. Additionally, the further you go, the more carbohydrate you will eventually use, even though you aren’t using as much at any given time. In endurance exercise, muscle glycogen can become so depleted that you may be forced to significantly reduce your pace. By consuming a larger-than-normal amount of carbohydrates before exercise, you can slightly increase muscle glycogen stores in order to delay, or eliminate, the need to drastically reduce pace.

What distance of race calls for carb-loading?

If you’re aiming to complete your first 5k race, or to establish a new personal best in the 10k, proper rest and a normal diet will ensure you have enough carbohydrate on board to achieve your goal. Cancel the party-size sub for one.

If you are aiming to do a half-marathon, things are a bit less clear. Lab research suggests that carb-loading could benefit athletes exercising for more than 90 minutes, particularly if your goal is to complete the distance as quickly as possible. But there really haven’t been enough studies done to determine just what kind of half-marathoner can benefit from carb-loading. It may be best to conclude for now that if you’re aiming for a PB in the half marathon, carb-loading is a good option as long as you don’t overdo it. Otherwise, go with the previous advice of proper rest and a normal pre-race diet. Maybe someone reading this has some personal experience (or maybe some group data!) to share?

If your goal distance is the marathon, then you will almost definitely benefit from pre-race carb-loading. Intensity and duration combine to determine how much muscle glycogen you will use, and whether you risk depleting it in your race. Elite male marathoners can complete 42.2 km in just over 2 hours, but because of their ability to maintain such a high exercise intensity (which requires more carbohydrate), they will deplete their muscle glycogen quickly. A runner aiming to complete a marathon in 4 hours won’t use as much carbohydrate at any given time, but will spend more time running, and will start with less muscle glycogen than the elite runner. In both cases, muscle glycogen will likely become depleted late in the race, before the finish.

To sum things up, if you have run a marathon and it seemed pretty hard in the last couple kilometers, you would have benefited from pre-race carb loading. Disclaimer: I do not provide any sort of guarantee that carb-loading will make the last few kilometers of a marathon any easier; you just might not slow down so much.

How much carbohydrate do I need to eat? For how long?

It seems like there are two types of carb-loading athletes. There is the common “night-before pasta-eater” (let’s call her Tracy) who gathers with fellow athletes for one last meal before the big day. Then there is the rare and elusive “week-long suffer-fester” (let’s call him Olaf), who swears by a protocol of several days of intense exercise with very low carb intake to deplete muscle glycogen, and then several days of reduced training and carb-loading to increase carb storage beyond normal values. You could argue that Olaf’s technique might result in higher pre-race glycogen concentration, and you could argue that Tracy’s technique might result in a more functional member of society during the week, with a slightly submaximal glycogen concentration on the weekend.

Is there a way for us to maximize pre-race muscle glycogen concentration while keeping our day jobs? Olaf’s technique is based on research from 40 years ago, and there have been a few updates since then. The current recommendations call for no “depletion phase”, and a brief 36-48-hour period of carb-loading before the event. That’s much more reasonable. But for those of us who wouldn’t mind an even shorter loading period, let’s look a bit deeper.

In 2002, “endurance-trained” athletes ate 10 grams of carbohydrate per kg body mass per day, over 3 days of rest. Muscle glycogen concentration reached a maximal level after just one day, remaining constant over the next 2 days. The researchers concluded that one day of carb-loading, combined with rest, is enough to optimally load the muscle with glycogen.

OK, so we’ve got it down to one day of loading. Great. But 10 grams per kg body mass? For someone who weighs 80kg (~175lbs), that’s 800 grams of carbs, or about 50 slices of bread! Let’s see if we can do something about this.

A 2011 study compared finishing times of two large groups of runners at the London Marathon. Average finishing time of the entire athlete pool was 4.5 hours, which is very comparable to average finishing time at most marathons. The day before the event, one group had eaten less than 7 grams of carbs per kg body mass, while the other group had eaten more than 7. No measures of muscle glycogen concentration were taken, but the group that had eaten more pre-race carbs ran over 10% faster than the group that ate fewer carbs. That’s a difference of about half an hour!

So it appears we have a compromise. For optimal pre-exercise carb-loading, you should start earlier and be more consistent with intake than Tracy, but you don’t need to go nuts like Olaf. Let’s arrive at this recommendation: Try to eat between 7-10 grams of carbohydrate per kg body mass per day, over 1-2 days before your event. Err on the higher carb side if you eat a good amount of carbohydrates on a daily basis, and on the lower side if you don’t normally eat a ton of carbs. An even lower amount of carbohydrate may still be effective for someone who has a low daily carb intake. In terms of time frame, favour the shorter protocol if you’re busy. You don’t want to have to explain to your partner how you got fired because you skipped work on Friday to down a couple pounds of potatoes.

Next time: The logistical (and social) challenges of actually consuming more than 7 grams of carbohydrate per kg body mass in one day. Find out if I chose to diversify beyond my requisite 34 slices of bread.
