Kamnik Saddle

Overview

Kamnik Saddle is a hors catégorie (HC) climb in Slovenia, running 8.2 km from a valley floor at 541 m to a summit at 1,454 m. That works out to a net elevation gain of 913 m over the distance, giving an average gradient of 11.2%. This is not a long climb by alpine standards, but the combination of length and pitch puts it firmly in the highest difficulty bracket. There is nowhere to hide on a wall this steep.

The number that matters most here is the gap between net gain and total ascent. You gain 913 m of altitude, but the road actually climbs 1,059 m in total — a 146 m difference. That means roughly 146 m of the climbing is spent re-gaining ground you lost on short descents or false flats. Undulation like this breaks rhythm and inflates the real cost of the effort well beyond what the average gradient suggests.

How the Gradient Unfolds

The 11.2% average is a blend, not a constant. It hides both easier links and ramps far steeper than the headline figure. Because of the 146 m of undulation, the profile is stitched together from repeated efforts rather than one smooth drag, and the steepest ramp will demand a hard, out-of-saddle surge.

• Short recovery or false-flat sections where the road briefly eases or tips downhill
• Repeated short climbing pitches that reset your rhythm again and again
• A steepest ramp well into the mid-20s or beyond, sharply above the 11.2% average

Pacing Notes

On a smooth climb you can chase even effort and let speed drift with the grade. Kamnik Saddle punishes that instinct. The undulation means even-speed pacing is impossible and even-power pacing is hard — you will spike above threshold on the steep ramps whether you like it or not. Anchor your ride to a target sustainable power output, then accept short surges above it on the walls while soft-pedalling the brief flatter links to bring your average back down. Use the FTP estimator beforehand to set that ceiling, and start conservatively: the 146 m of hidden climbing means the back half costs more than the profile implies.

Gearing

Gearing here is governed by the steepest ramps, not the average. On a climb this steep, run a compact (34-tooth inner ring) at minimum, and consider a sub-compact if you have one. Pair it with a wide-range cassette — a 34×32 or, better, a 34×34 low gear will let you keep cadence up rather than grinding into the red on the steepest pitches. Check your setup before the ride; the day of an HC wall is the wrong time to discover your low gear is too tall.

Summary

• Length: 8.2 km
• Average gradient: 11.2%
• Maximum gradient: 39.17%
• Net elevation gain: 913 m
• Total ascent: 1,059 m
• Category: HC

Kamnik Saddle rewards riders who respect the numbers: short enough to tempt you into starting hard, steep and undulating enough to make you pay for it. Set a realistic power ceiling, fit the right gears, and treat every ramp as its own effort.
