Difficulty breakdown: This HC climb covers 19.5 km for 1118 m of elevation gain, with an average gradient of 5.7%. It starts gently (5% from km 0-1), then km 2 to 5 ramp up to 9%, the hardest section. After a near-flat, even slightly downhill stretch between km 11 and 14, the finale packs a kick to 8% at km 14-15, then sustained gradients of 7% at km 17-18 and 8% at km 19-19.5.
Tips for managing your effort:
1. Pace your start. Don't go out too hard on the 5% of km 0-1, or you'll have nothing left for the 9% block from km 2 to 5.
2. Recover in the km 11-14 section. The gradient is easy to negative here, so it's the perfect time to drink, eat and top up before the 8% kick at km 14-15.
3. Keep the finale steady. From km 17 to 19.5, where gradients stay at 7 and 8%, choose a gear that lets you spin smoothly without surging, and stay seated on the steepest parts.

The climb itself is described as a physical challenge, with riders simply saying that "the mountain is hard". While the condition of the road isn't really detailed, the overall vibe is shaped by the visible presence of soldiers and the surrounding propaganda, which is a strong feature of the experience according to the accounts.
