We continue our analysis of two distinct running styles, using motion analysis and high speed video of top Ironman pros Craig Alexander, Torbjorn Sindballe, Chrissie Wellington, Cait Snow, Mirinda Carfrae, and Richie Cunningham. We also look at a regular guy running both styles at different paces. We believe that the Glider style may be better for most long course triathletes and every day runners, in that it requires less energy at a given pace and is less likely to cause injury.
