At 6'6" and 225 pounds--and 42 years old on race day--I'm probably one of the few (if not the only) clydesdale-master in the solo division! Which will make me feel better about taking my time getting around the course. I've been on this course twice in challenging conditions: once in Primal Quest 2006, when the temperature was over 100F and the water stations ran out of water, and in the "flood" at the 2004 24 Hours of Moab.
