A runner who also does triathlons
Michael is a runner who does triathlons. His marathon PR before PowerCranks was about 2:40 so he was good but not exceptional. In this video (recorded in 2008) he relates the substantial run benefits he saw almost immediately after starting on the PowerCranks. Since that time he has started to focus more on running as he saw himself improve. In June of 2009 he "hit a new 1/2 marathon PR 1:11 and a new 10k pr 32min, and was feeling capable of running a 2:25 marathon if everything goes right.
