Difficulty breakdown: At 19 km for 1351 m of elevation gain and an average gradient of 7.1%, the Sikkim Gnathang from Asam is a seriously demanding HC climb. The first 15 km are nearly relentless, with steady gradients between 5% and 7% and no real chance to recover. The flat section from km 15.0 to 16.0 (2%) and the short descent from km 16.0 to 17.0 (-4%) offer a welcome breather, but the almost flat final stretch from km 17.0 to 19.0 (1%) can hurt when your legs are already cooked.
Tips for pacing yourself:
1. Stay steady above all From km 0.0 to 15.0, hold a constant rhythm and resist the temptation to go out too hard on the early 6% ramps.
2. Make the most of the flat Use the 2% section from km 15.0 to 16.0 to eat, drink and get your legs turning again before the descent.
3. Save your legs for the finish On the almost flat stretch from km 17.0 to 19.0, keep a high cadence and an easy gear so you don't end up running on empty.
