I love hot and cold therapy, but it’s tricky to find in London. Whenever I’m in LA or New York, I head to Remedy Place – it’s unreal, Drake goes there. It’s all about recovery: think infrared light sauna, acupuncture and cupping rooms, cryo chambers and, my favourite, hyperbaric chambers, which pump oxygen round the body so you recover like a beast. It sounds hardcore, but I’m into it. When I’m training for something as serious as this challenge, I have this switch in my brain that flicks. I can get obsessed with training and making sure I’m performing at my best. I’m ultra in every way.
