Thought you had a hypoxico?
i do.... but we live at 6k and instead of sleeping in the tent we do sessions wearing the mask (connected to hypoxico) a lot of research (got this recommendation from dude at hypoxico) that the workouts are even more beneficial than sleeping in a tent. sleep quality suffers too much.
Got it. I did passive altitude sim much the same way on the "Airfit" system and protocol. Totally works; about 10% faster at sea level and little to no RPE difference at Xterra Snow Valley.
