Mount Hunt Divide cycling climb profile
Mount Hunt Divide is a category 1 climb in the US that asks for sustained aerobic control more than repeated accelerations. On paper, 18.4 km at 5.52% looks manageable, but that average only tells part of the story. The climb gains 1015 m from a start elevation of 1941 m to a summit elevation of 2956 m, and the total ascent is 1024 m, which means the road is essentially committed to going uphill rather than giving back meaningful elevation.
That matters tactically. A climb with very little net-versus-total-ascent difference rarely gives riders much free recovery. Even when the gradient eases, the pressure stays on because the road keeps trending upward. The danger is treating the 5.52% average as a pacing target and then finding the harder pitches too costly later on.
How the gradient unfolds
The defining feature is duration. At 18.4 km, Mount Hunt Divide is long enough that early overpacing will compound. The average gradient sits in the steady-climbing range, but the maximum gradient of 14.9% shows there are sharper sections where torque demand rises quickly.
That combination makes this a climb of rhythm disruption. Most of the effort should feel controlled and repeatable, but the steepest ramps can force a shift from seated aerobic climbing into lower-cadence muscular work if the gearing is too ambitious. Because the climb finishes at 2956 m, the final part can feel more expensive than the same gradient lower down, especially if the early kilometres were ridden too close to threshold.
Pacing notes
The smart ride is conservative early, then progressive if the legs are still responding.
- Start below your sustainable climbing effort, not at it.
- Use the 5.52% average as a description of the whole climb, not a prescription for every kilometre.
- Keep a ceiling on the steeper ramps rather than chasing speed over them.
- If riding by power, anchor the main effort around your known climbing range and avoid repeated surges above /glossary/ftp unless the ramp demands it.
The key is to protect cadence and breathing. A category 1 climb with 1015 m of net gain rewards riders who spend energy evenly. If you burn matches early, the upper half becomes a management exercise rather than a performance.
Gearing notes
Bring a low enough gear for the 14.9% maximum gradient, not just the 5.52% average. The climb is long, starts already at 1941 m, and tops out at 2956 m, so grinding a hard gear on the steepest sections is a poor trade. A setup that lets you stay seated and keep cadence under control will usually beat a bigger gear ridden in survival mode.
For most riders, the practical goal is simple: choose gearing that makes the steep ramps manageable while still allowing an efficient rhythm on the sustained middle gradients. Mount Hunt Divide is not just a test of peak power. It is a test of whether you can ration effort across 18.4 km of almost continuous climbing.
