This weeks show Tom is solo, he chats through Eliud Kipchoges incredible Sub 2hr record, The IRONMAN World Championships and Ultra X Jordan. What do you think of the controversial Nike Vapour Fly 4%? Is the sub 2hr a legit record or not? Tell us your thoughts at @ifendurance on instagram or mail [email protected].

Tom answers two questions this week, the first is when is your HR too high for running? At what point are you in the ‘danger zone’? The second is based on run intervals, work time vs rest time. What intervals elicit certain gains? Got more questions? Send them in to @ifendurance or mail us!
