In this episode, we discuss his transformation from around 125kg down toward 80kg, the unconventional approach he used to lose weight while staying injury-free, and why walking, varied movement and high-frequency training may be underrated tools for endurance athletes. We then go deep into marathon training, breaking down some of our favourite sessions including 25 x 600m, 1K on/1K float, progression long runs, 2K repetitions, long marathon-pace intervals and the classic 2 x 10K marathon dress rehearsal. We also discuss sleep consistency, post-workout carbohydrate intake, creatine, Nomio, sauna and heat adaptation, occasional "hero sessions," energy drinks, and the importance of considering heart health when using stimulants.
