Col de Bân Quang

Col de Bân Quang cycling climb profile

The Col de Bân Quang is an 11.4 km category 1 climb in Vietnam, rising from 84 m to 793 m. With a listed average gradient of 6.2% and a maximum gradient of 11.3%, it sits in the awkward middle ground that matters in real riding: not so steep that it is only about survival, but long and hard enough that poor pacing will catch up before the summit.

The headline number is the average gradient, but the key detail is the gap between that 6.2% average and the 11.3% maximum. That tells you this is not a perfectly metronomic drag. Even if the climb is broadly manageable, there are steeper sections that will force a decision: stay seated and absorb the torque, shift early and protect cadence, or stand briefly and risk spending more than planned. On a climb of this length, those small choices compound.

How the gradient unfolds

From bottom to summit, the basic demand is sustained climbing. The road gains 709 m between the start and the top, with total ascent listed at 693 m, so the profile should be treated as a long net-positive effort rather than a rolling climb where descents offer meaningful recovery.

At 6.2% average, the opening should not be ridden like a short hill. The right approach is to settle into a gear that feels almost too controlled early, especially because the maximum gradient reaches 11.3%. Those steeper pitches are where riders who start at or above /glossary/ftp will be forced into repeated surges. That may feel sustainable for the first part of the climb, but it usually turns the final kilometres into damage control.

Pacing and gearing notes

Ride the Col de Bân Quang as a steady aerobic climb with room for short pressure changes, not as a climb to attack from the base. The best pacing strategy is simple: keep the first section under control, avoid chasing speed on easier moments, and save enough muscular reserve for the steeper ramps.

Practical gearing matters because the maximum gradient is nearly double the average. If your easiest gear only feels comfortable on moderate gradients, it may become a limiter when the road pitches up. Choose gearing that lets you keep pedalling smoothly when the climb reaches its steepest grade, rather than forcing low-cadence grinding too early.

For stronger riders, the temptation will be to ride the average gradient aggressively. The better move is to cap the effort until the final portion, then use any remaining margin near the top. For endurance-focused riders, the goal is even simpler: keep the effort repeatable, avoid spikes, and let the climb come back to you.
