Subject: RE: training in higher altitudesI saw this route in northern Georgia that looks like a pretty good climb.  Here's another view from Google earth.  So it does look like indeed there are Mountains in Georgia with some pretty gnarley climbs. I live at 3600 feet. The altitude does play a minor role. For running the perceived level of exertion is higher but the actual drop in speed is maybe 10 sec a mile at most. For cycling there does not seem to be any difference at all. I've read different sources. One source said the measurable change in performance can occur as low as 1500 feet. There is a canyon near us that is at an elevation of 2600 feet at the bottom. Athletic performance at that level appears to be equal that of sea level at least for me. I'm sure it's a little different for everyone. For me the "change" seems to happen somewhere around 3200 feet or so. One other source I read said that your brain picks up on the lower oxygen content in your blood and adjusts down muscle recruitment and cardiac output. Part of the reason they say to live at altitude and train at sea level. I wouldn't worry so much about the air as the steepness of some of these climbs. |
