Pereval Dalari

Pereval Dalari cycling climb profile

Pereval Dalari is a category 1 climb in RU, and the headline numbers tell you this is more of an endurance management problem than a simple steep-climb effort. The road runs for 80.9 km, starts at 837 m, and tops out at 3351 m, gaining 2514 m from bottom to summit. The average gradient is only 3.11%, but that number is deceptive because the maximum gradient reaches 19.93%.

That contrast is the key to understanding how this climb rides. An 80.9 km ascent at 3.11% cannot feel like a continuous wall. The elevation gain is spread over a very long distance, so large portions should ride as shallow climbing where aerodynamics, fuelling, and rhythm matter as much as raw climbing power. But the near-20% maximum gradient means the climb also contains at least one genuinely severe ramp, and likely enough pitch variation that treating the whole ascent as a steady tempo climb would be a mistake.

How the gradient unfolds

Without intermediate split data, the honest read comes from the relationship between length, average gradient, and maximum gradient. The bottom-to-summit profile is long and gradual on paper, but punctuated by steep sections that can disrupt pacing. The low average gradient invites overconfidence early because speed will remain relatively high for a climb, especially if the opening slopes are mild. That is where riders can quietly burn too much energy before the altitude gain has really accumulated.

The practical consequence is that Pereval Dalari rewards restraint. The climb asks you to stay efficient for a very long time, then absorb much steeper pitches without letting those short sections dictate the entire effort.

Pacing and gearing notes

Pace Pereval Dalari by duration and energy cost, not by the 3.11% average alone. For most riders, the early and middle sections should sit below /glossary/ftp, with any sharper ramps treated as controlled surges rather than attacks. If you ride the shallow gradients too hard, the 19.93% maximum pitch becomes much more expensive later.

Gearing should be chosen for the steepest section, not the average grade. A setup that feels comfortable on a 3.11% climb may become overgeared when the road kicks up close to 19.93%. The priority is keeping cadence available when the gradient bites, because grinding the steep ramps after hours of climbing will compound fatigue quickly.

The best approach is simple: ride the long shallow sections smoothly, fuel early, avoid chasing speed on the easier gradients, and keep a reserve for the steepest pitches. Pereval Dalari is not defined by one number. It is the combination of 80.9 km of climbing, 2514 m of net gain, and a maximum gradient steep enough to punish poor pacing.
