Tomorrow is the Dash of Doom race in Calgary, an annual event where runners are encouraged to show up in more than just nylon shorts and florescent shirts. A fundraiser for the Alberta Animal Rescue Crew Society, the pet-friendly race is a family event that offers runners a chance to burn off some of that pre-Halloween candy. It also marks a great (fun) warm-up for the Calgary Marathon on May 29. Please, folks, sincerely, anyone attending (and runners who find themselves justly inspired), send us your photographs! Every picture we receive of runners in Halloween costumes will be posted on our blog throughout next week. Let’s see if we can’t get 100, and make this the Best Week Ever leading into Halloween! Here are some pictures we love from last year’s incredible Dash of Doom.
