Endurance athletes are either extremely driven or crazy. Leadville Race Series participants are both. Set high in the Rocky Mountains in Leadville, Colorado, Leadville challenges mountain bikers and runners to be at their absolute best to complete its grueling 100-mile course. Racers who finish in under 12 hours get pride and a big, shiny belt buckle. I have enough belts. That's why I just write about it, not join it.
