In this episode the team (Richard, Andy & Mark) discuss marginal gains, we try to best answer a listeners training question regarding his training approach for 2 x 70.3 races with a four month gap. Richard also chats about how to really get good at swimming - no short cuts, or hacks though. Mark interviews Matthew Pritchard (AKA) Dirty Sanchez, who has stopped all his drug and booze fuelled antics for a more extreme lifestyle. Matt now challenges his mind and body in a different way, extreme physical challenges, multi disciplined events including Ironman, and undertaking a personal challenge of completing 30 x 70.3 IM in 30 days and much much more. Warning he does swear more than Mark! Enjoy
