as in that in klagenfurt austria. 446m.
does this matter to a fella who lives and trains all year long at sea level?
Have a look at this:
the maximal aerobic ability (VO2 max.) is reduced by approximately 1% for every 100 meters (~ 300 feet) above 4500 feet in recreational athletes and can be detected in highly trained athletes at altitudes as low as 1500 feet above sea level."
