The Whistler 50 ultra-marathon is a grueling event in which 25% of this year's runners didn't even make it to the finish line, the definition of success is a matter of personal perspective, and individual experience easily eclipses competition. Comparing runners by traditional ordinal ranking isn't a very meaningful exercise.
