Difficulty breakdown: The Chang La from Koyül covers 6.9 km for 357 m of elevation gain, with an average gradient of 5.2%, which puts it in Category 1. The real challenge is the consistency: nearly every section sits between 4% and 8%, with no real chance to recover. The steepest stretch is at KM 0.0-0.5 at 8%, and KM 2.5-3.0 at 7% is the most demanding part of the middle section. Only KM 5.5-6.0, at 2%, gives you a proper breather before the finale.
Tips for managing your effort:
1. Pacing the start Don't go out too hard over KM 0.0-0.5 at 8%. It's tempting to hammer it when there's still a long way to go.
2. Riding at a steady effort On the 5 and 6% sections, pick a gear that lets you keep a smooth, steady cadence rather than burning through your reserves.
3. Making the most of the flat Recover properly over KM 5.5-6.0 at 2%, taking on food and fluids before the last kilometres at 4%.
