The 41-year-old running coach, podcast host and all-round hype man from Streatham has had a busy few months, so it’s become more important that he fits some R&R into his schedule. When he’s not podcasting, he’s recording workouts as one of the coaches on the Nike Run Club app — some 80,000 people a month tune in to his sessions — or creating exceptionally fun “Vibercise” workouts on Instagram.
