Tulung La

Tulung La cycling climb profile

Tulung La is not complicated on paper, but it is severe in execution. The climb runs for 26.3 km, starts at 3,523 m, and tops out at 5,149 m. That means the defining feature is not just the 6.18% average gradient, but the fact that the entire effort happens high enough for pacing mistakes to compound quickly.

The headline number is the 1,626 m net elevation gain. Spread across the full distance, that makes Tulung La a long, sustained aerobic climb rather than a short fight against one wall. But the 17.73% maximum gradient changes the way it has to be ridden. An average just over 6% can tempt riders into settling slightly above sustainable power early. On Tulung La, that is risky, because the steepest ramps are sharp enough to turn a small overreach into a real cost.

How the gradient rides

With only the total profile statistics, the cleanest read is this: Tulung La is a long climb built around sustained pressure, interrupted by gradients steep enough to demand respect. The average gradient tells you there is no easy way to fake the climb. The maximum gradient tells you there will be moments where cadence, torque, and gear choice matter as much as raw fitness.

From the bottom at 3,523 m, the best approach is to treat the first part as controlled climbing, not as a chance to bank time. The climb has too much vertical gain for early aggression to hold value unless you are clearly under threshold. By the time the road is pushing toward the summit at 5,149 m, the same power will feel more expensive, and the cost of grinding through a steep pitch will be higher.

Pacing and gearing notes

Ride Tulung La from the start as an HC climb, not as a moderate climb with a few hard sections. The correct pacing anchor is sustainable climbing power, ideally below your true /glossary/ftp until the climb has declared itself. If you have to stand and force the gear on the steepest gradients, the setup is too hard or the pacing is too ambitious.

Practical priorities:

• Choose low gearing that leaves a usable cadence when the road reaches double-digit gradients.
• Keep the opening effort conservative, because 26.3 km gives every early surge time to come back.
• Avoid chasing the 6.18% average as if it describes every section. The 17.73% maximum is the warning label.
• Fuel and drink early, since the duration and altitude make late recovery harder once intensity has drifted too high.

Tulung La is a climb for riders who can separate discipline from weakness. The profile rewards steady pressure, but only if the gearing is light enough and the pacing is patient enough to survive the steepest ramps before the summit.
