Elsie is a doctor, North Face sponsored trail ultra runner, 2:33 marathoner, and a returning guest on the T&E podcast. On the episode we talk about her recent win at Nice Côte d'Azur by UTMB, her winter Bob Graham round record, and reaching her limits with heat stroke at the Calamorro Skyrace. We touch on some of Elsie’s training strategies, including her 40% incline treadmill and depriving herself of oxygen in bed and while on the treadmill with an altitude mask. All that and more. PS. The audio quality is fairly poor on this one. We’ll try to make sure it doesn’t happen again.
