Tips

Difficulty breakdown: The Dengong Ka pass (邓公卡), starting from Mayang, is an HC climb covering 21.5 km with 1151 m of elevation gain, at an average gradient of 5.4%. The start is already tough with 10% on km 0-1, but the real challenge comes in the second half, from km 13 to km 21, where the gradient varies between 4% and 8%, with 8% stretches on km 15-16 and 18-19. The flat or downhill sections on km 4-6 offer a bit of respite, but the effort stays long and nearly continuous.

Pacing tips:

1. Start easy from the first kilometers The 10% on km 0-1 tempts you to go out too hard. Settle into a steady rhythm right from the bottom so you don't burn through your matches before the long final drag.

2. Recover on the flat section from km 4 to km 6 Make the most of the 0% stretches on km 4-5 and 5-6 to drink, fuel up and get your breath back before the climb continues.

3. Manage your effort in the final part Between km 13 and km 21, you'll be grinding through 5 to 8% gradients, so don't go into the red. Save some energy for the steepest ramps on km 18-19 and 20-21.
