But since the genetic aspect of acclimitization and high altitude performance is outside our control, maximize the potential in what we can control. Like being healthy , hydrated going into the experience and maximize your physical potential.
Let's not forget though that aerobic and anaerobic fitness can only benefit ones altitude performance. Doing ones best to work at and then maintain fitness in these disciplines, should be included in ones training routine.
