Altitude training is the practice by some endurance athletes of training for several weeks at high altitude, preferably over 2,400 metres (8,000 ft) above sea level, though more commonly at intermediate altitudes due to the shortage of suitable high-altitude locations.ltitude training works because of the difference in atmospheric pressure between sea level and high altitude. At sea level, air is denser and there are more molecules of gas per litre of air.
Altitude training may depend on the individual as to what altitude is optimal. For example, the great American mile runner, Jim Ryan, didnât like altitude training. He felt like he couldnât recover and that he couldnât do the same workouts at altitude due to the limitations. He preferred to train at sea level.
