Historically IHT and altitude training has long been used for distance running since the 1960's. Traditional altitude training with the - live high, train high - method requires a minimum of 3 weeks of living at high altitude to get acclimated. Thereafter, when you relocate to a low altitude racing venue to compete the benefits of altitude exposure begin to disappear about 2 weeks later and the athletes have to return to altitude for a top up exposure. . With AltoLab you can do get your altitude exposure at home, anywhere in the world, and it only requires 15 days to get acclimated. How, because AltoLab employs a progressive, IHT program where you only use short, 6 min intervals at altitudes that progress from 10,000 up to 20,000 ft + equivalent. The benefits of this type of IHT last for 2 weeks and thereafter you can top-up by using the AltoLab for just 5 days with a 15 day break afterwards. The more top-ups you complete the greater your altitude acclimation becomes. The notable distance runners we have using the AltoLab system include USA Champions Shannon Rowbury and Leonel Manzano.
