Tomorrows ride, from Golden to Boulder, even though lower altitude will still be 85% higher than the Alps.
Our ride on Friday was around 8,000 ft and our Sunday ride from Keystone to Montezuma was from 9,000 - 10,200. I really felt both rides, having recently been in Wisconsin for 3 weeks and I don't normally train at that altitude.
Local news interviews from the racers all comment about how the altitude is affecting them.
Thanks Colby and Kathi for doing the math for me. 
Chris Horner has mentioned the altitude a few times, and Ted King said he ralphed during yesterday's stage.
