"After a few weeks of using your system, I was already beginning to feel the positive effects of sleeping high.  I experienced rapid improvements in workouts and set several personal bests.  Most recently, I lowered my half-marathon best by one minute.  The Altitudetech altitude tent system has definitely played a vital role in my long term development.  I am able to do more consistent quality running and regenerate between sessions more quickly than before.  Physiologically, my hematocrit has improved by 4 points.  It's clear your system is a great supplement for training and racing, thank you!"
