Jarman Gap

Jarman Gap cycling climb profile

Jarman Gap is a short, concentrated climb in the US: 4.4 km at an average gradient of 6.88%, rising from 229 m to a summit elevation of 535 m. The profile data lists 306 m of net elevation gain and 289 m of total ascent, which points to the same practical conclusion for the rider - this is not a long aerobic drag, but it is steep enough to punish poor pacing.

The key number is the maximum gradient of 12.93%. On a climb averaging just under 7%, that tells you the effort is unlikely to feel perfectly even. The average is manageable on paper, but the upper gradient means there are sections where momentum fades quickly and cadence can collapse if you arrive over-geared or already above threshold.

How the gradient should be ridden

Because the supplied data gives the overall length, average gradient, and maximum gradient rather than a detailed ramp-by-ramp breakdown, the safest read is to treat Jarman Gap as a climb with meaningful variability inside a relatively compact distance. At 4.4 km, there is not much room to recover from an early mistake. If you ride the opening as if the whole climb sits neatly at 6.88%, the steepest pitch near 12.93% becomes the moment that exposes the overreach.

The better approach is controlled pressure from the bottom, then a progressive lift only once the climb has declared itself. For riders pacing by power, that means starting just below sustainable climbing effort rather than chasing speed. If you use /glossary/ftp as your anchor, avoid treating the first minutes like a test. The climb is long enough that burning matches early will matter, but short enough that a disciplined finish can still be hard.

Gearing and pacing notes

A maximum gradient of 12.93% makes low gearing valuable, even if the average gradient is not extreme. The mistake is choosing a gear for the 6.88% average rather than the steepest section. You want a small enough gear to keep cadence alive when the road kicks up, because grinding through the steepest pitch will raise muscular load and make the final part of the climb feel longer than the distance suggests.

Practical execution:

• Settle early and let speed be the variable, not effort.
• Keep one easier gear available before the steepest ramps arrive.
• Stay seated if traction and cadence are stable, but do not be afraid to stand briefly to reset momentum on the 12.93% sections.
• Save the real acceleration for the final portion, once the risk of another steep pitch matters less.

What it means

Jarman Gap is a category 2 climb by the supplied classification, and its difficulty comes from density rather than duration. The numbers describe a climb that rewards patience, appropriate gearing, and the ability to absorb short steep gradients without letting the effort spike out of control. Ride it smoothly, and 4.4 km is manageable. Ride it impatiently, and the maximum gradient becomes the defining feature of the climb.
