Sprints and Trophies

My trophy finally came
emblazoned with my name.

I do a lot of endurance events. I've run a lot of marathons. I've done 2 Ironman-distance triathlons. But when it comes to competitive standings in a race, I always do better in the shorter distances. My medals for placing are almost always "sprint" races, which often involve a 5k (3.1 mile) run.

I suspect that my muscles lean toward the fast-twitch side,

but I've trained them to go for the slow-twitch ride.
