Sedlo

Overview

Sedlo is short in distance but relentless in character. Over just 1.9 km it hauls you from 1567 m to a summit of 1795 m, a net gain of 228 m packed into a climb that never lets the road go flat. With an average gradient of 11.79% and a maximum pitch of 16.64%, this is a Category 2 effort that punches well above its length. There is nowhere to hide here: from the moment the ascent begins, the numbers demand respect, and the thin mountain air near 1800 m only sharpens the challenge.

How the Gradient Unfolds

The defining feature of Sedlo is its consistency. An 11.79% average across 1.9 km means the road is steep almost everywhere, with only modest variation between the shallowest and steepest sections. The 16.64% max sits roughly five points above the average, so the hardest ramps are noticeably harder than the baseline but not wildly out of proportion — this is a wall, not a series of spikes with recovery in between. Expect the gradient to bite early and hold. The recorded total ascent of 216 m is slightly below the 228 m net gain, meaning the profile climbs almost monotonically with barely a metre given back. In practical terms: pick a rhythm and defend it, because the road will not offer you a breather.

Pacing Notes

On a climb this steep and this short, pacing is about restraint at the base. The temptation is to attack the opening ramps, but with 11.79% sustained for the full 1.9 km, going into the red early will cost you dearly before the summit. Ride the first third just under your threshold and let the effort build. Knowing your FTP is essential here — Sedlo is short enough that a strong rider can hold close to threshold the whole way, but only if that number is calibrated honestly. If you are unsure of yours, run the numbers through the FTP estimator before you commit to a pacing target. Aim to have your hardest effort left for the 16.64% pitches rather than spending it on the lower slopes.

Gearing

With a sustained 11.79% and ramps touching 16.64%, gearing is not a place to be macho. For most riders a compact 34-tooth chainring paired with a wide cassette is the right call. A 34×32 will get many trained climbers up at a workable cadence, but on a gradient this steep for 1.9 km, the extra range of a 34×34 is worth having — it lets you spin rather than grind, which protects your legs across a climb where the pressure never eases. If your bike allows an even larger sprocket, take it; you will not regret the security on the steepest sections.

Summary

Sedlo is a concentrated, high-quality climb: brief, brutally steep, and demanding a disciplined effort from base to summit. Respect the gradient, gear low, and pace the opening, and this Category 2 ascent rewards you with a hard-won 1795 m summit.
