Tips

Difficulty analysis: The Damthang Pass is an HC climb of 18.5 km with 1648 m of elevation gain, at an average gradient of 8.9%. The first part, from km 0 to km 10, is tough and steady, with gradients between 5% and 11%, including 11% at km 5-6 and km 10-11. The hardest point comes at km 12-13 with a 16% ramp, right after a short descent at -6% between km 11-12 that drops you 56 m. Beyond km 13, the profile eases off noticeably, with gradients between -1% and 4% all the way to the finish.

Tips for managing your effort:

1. Pace yourself from the bottom. The first 10 km have a lot of gradient changes, so don't go out too hard and save some energy for later.

2. Make the most of the descent at km 11-12. This short -6% section is your chance to recover, drink and eat, then tackle the 16% ramp at km 12-13 with a steady cadence.

3. Turn the pace back on across the final plateau. Between km 13 and km 18.5, with gradients of 1 to 4%, you can push the pedals harder and pick up speed to finish the climb strongly.
