This trip involved only 420 miles of biking in the Rockies with 26000' of climbing.
The climbing was actually easier for me than descending. The speeds of the descents and high danger kept my hands on the brakes. After each hard day of riding, I was in my tent catching up on work with my laptop. Sleeping was never a problem even at the high altitudes. It was freezing each morning with frozen dew on the tents.
