Joel Filliol, Coach of Seven World Championship Titles: You Need Less Intensity Than You Think

Joel Filliol has coached four athletes to seven triathlon World Championship titles: Mario Mola, Vincent Luis, Katie Zaferes and, this year, Vasco Vilaça. On his third appearance on the show we cover how the squad's training has (and has not) changed over a decade of titles, the training week and progressive sessions behind them, how much intensity is actually enough, and how the same principles apply to age-group triathletes on 10 to 15 hours a week.
