Hiadeľské sedlo

Overview

Hiadeľské sedlo is a Category 1 climb that asks for genuine respect. Over 9.5 km it averages 7.21%, lifting you from a valley floor at 418 m to a summit of 1104 m — a net gain of 686 m. The total ascent of 661 m tells you the road climbs almost the entire way, with only a sliver of flat or false-flat relief mixed in. That combination of length and steepness puts it firmly in the tier just below the hardest climbs, and the 19.2% maximum gradient means there is a sting hiding somewhere in its length.

How the Gradient Unfolds

A 7.21% average is deceptive on a climb like this, because averages smooth over the pain. With a maximum of 19.2%, the pitch more than doubles the mean at its worst, and a ramp that steep on a 9.5 km climb is rarely a single isolated wall — it signals a road that pulses between merciful stretches and lung-burning kickers. Expect the gradient to sit in a sustainable band for long sections, then spike hard where the terrain forces the road upward. The gap between the 686 m net gain and the 661 m total ascent is small, roughly 25 m, which confirms there is very little descending to break the rhythm: once you start climbing, you keep climbing.

Pacing Notes

The smartest way to ride Hiadeľské sedlo is to anchor your effort to your FTP rather than to how the opening kilometres feel. At 9.5 km, this is a sustained tempo-to-threshold effort for most riders, so hold something in reserve for the 19.2% ramps — those are the moments that blow pacing plans apart. Aim to arrive at the steepest pitches with enough headroom to absorb a short surge above threshold without redlining. If you are not sure what your sustainable number is, run it through the FTP estimator before you commit to a target, then ride the first few kilometres slightly under it. On a climb with this much vertical, going out too hard costs far more than starting conservatively.

Gearing

Gearing is where you win or lose on the steep ramps. With an average of 7.21% and pitches touching 19.2%, most riders will want a compact chainset paired with a wide-range cassette. A 34×32 is the sensible baseline and will carry strong climbers through the bulk of the 9.5 km at a workable cadence. But if you weigh a little more, ride at a lower FTP, or simply want to protect your knees on the 19.2% sections, size up to a 34×34 — that extra sprocket keeps your cadence spinning rather than grinding when the road bites hardest. On a 686 m ascent, the lower gear is insurance you will be glad to have.

Summary

Hiadeľské sedlo rewards patience and punishes bravado. Pace it off your FTP, gear low enough for the 19.2% ramps, and let the 686 m of climbing come to you a kilometre at a time.
