Living and training at Utah’s high altitudes has definite advantages for a distance runner (as adaptations to the reduced amount of oxygen in the atmosphere at higher altitudes). Altitude runners develop increased red blood cell volume and increased hemoglobin (the molecule in red blood cells that binds and carries oxygen).
There is one distinct disadvantage for runners who train at higher altitudes. Altitude runners aren’t able to train at the same intensity as their sea level counterparts due to that same reduction in oxygen availability. The “Live High Train Low” philosophy of distance training incorporates the advantages of altitude training most of the time, but adds periodic workouts at higher running velocities while breathing sea level concentration air.
By combining the two conditions, runners not only maintain the enhanced aerobic capacity developed through living and training at altitude, but also improve their neuromuscular capabilities (speed and economy) through the sea level intensity workouts.
Supplemental oxygen sessions can be performed as part of a TOSH designed training program, or you can schedule session as an addition to your training process on a session by session basis.
