Summit member for 3 months. Can’t speak more highly of Altitude as a “semi-extreme” athlete. Amazing facility and staff, the benefits of altitude training were remarkable for me. I’ve raced ultras for years, joined Altitude with an aggressive race schedule (3 ultras and a marathon major within 11 weeks) and exceeded all expectations with a couple PBs. With lower overall intensity I’m faster than I have been before. I’ve never enjoyed going to gyms before, but Melanie and her team have made a unique and valuable space to train for extreme activities. Highly recommend
