Adam Bohach, 27, Clinton, Iowa
A high school science teacher, Bohach has a thing or two to teach his students about being a fast triathlete. He wrapped up his final amateur season ranked first among men ages 25-29 by USA Triathlon (USAT), scooping up big wins at the Hy-Vee 5150 U.S. Championships in September and topping his age group at Ironman Racine 70.3 (his 4:12:06 finish was good enough for ninth overall, beating several pros). Bohach is also an accomplished runner, clocking 2:26:25 at Grandma’s Marathon in June and a 25:45 8K on the roads in 2010. Bohach, a biology major while at Luther College in Cedar Rapids, Iowa, is clearly a student of the sport: His senior project involved VO2, lactic acid, and cortisol levels in endurance trained athletes, for which he was awarded an NCAA post-graduate scholarship.
