Grade Question?(3 posts)

Grade Question?netso

If you have a hill that has a 6% grade, what is the difference if this hill is at sea level or 3000 ft?
Maybe I am missing something, but it seems the same to me?

The only difference is that the second hill is 3000 feet higher than the first. Otherwise, they are the same. :)

It's just an equation. 2 + 2 = 4 at sea level. The answer is the same at 3000 feet.

The differnce is that almost everything is harder at elevation. Unless and until you have been at elevation for at least 10 days. So a 6% climb at sea level (were you are aclimated i.e. red blood cells are carring enough o2 to you mucles given the density of air). Whereas, at elevation the air is thinner and it takes time for your red blood cells count to adapt to the tinner air (increase in number so they can carry the required o2 to the muscles)....

The beauty is that you go train at elelation (increase you red blood cell count) then come down to sea level and ride/race..you'll be an animal...
