Riding on one of the world's most beautiful roads - The Yunnan Highway. Lhasa to Zhongdian. The road is not flat for a meter, all the time up and down. Two passes over 5000m and over a dozen over 4000m. At some times you're down in pockets of sub-tropical rain forests at 1800m, at others on alpine, ice cold passes.
A challenge for any cyclist!

On the photo, the cyclist is on approx. 3000m, the surrounding peaks are roughly 7000m high.
