Znachsattel

Overview

Znachsattel is a Category 1 climb in Austria, running 17.7 km from a start elevation of 921 m to a summit at 1,948 m. Over that distance it delivers a net elevation gain of 1,027 m at an average gradient of 5.8%. On paper that reads as a long, steady grind — a mid-single-digit average across nearly eighteen kilometres.

The paper number lies. Total ascent on this climb is 1,569 m against just 1,027 m of net gain, meaning you actually climb roughly 542 m more than the elevation profile's endpoints suggest. That gap comes from undulation: descents and false flats you have to reclaim. In practice you'll do the vertical work of a much bigger mountain, and your legs will register the total ascent, not the tidy net figure. Budget your effort against 1,569 m, not 1,027 m.

How the Gradient Unfolds

A 5.8% average hides both the rolling terrain and the sharp pitches buried inside it. With 542 m of climbing that doesn't show up in the net gain, expect the road to give back altitude and then demand it again — the average is diluted by every metre you descend. That means the climbing sections are steeper than 5.8% to compensate.

• Flatter and recovery sections where the road eases or tips slightly downhill — resist coasting hard, you'll pay it back
• Repeated short climbs stacked through the middle, each one resetting your effort
• The steepest ramp, well into double digits, where you'll need your lowest gear and a controlled cadence

Pacing Notes

Even-speed pacing is a trap here. Holding a constant km/h forces your power spikes on every ramp and lets it collapse on the flatter sections, spiking your fatigue. Instead, ride to even effort: hold a steady sustainable power output and let your speed rise and fall with the terrain. Fast on the shallow bits, patient on the steep ones.

If you don't know your threshold, run the numbers through the FTP estimator first. On an undulating 17.7 km climb, anchoring to a power target rather than a speed target is what keeps you from blowing up on the third or fourth ramp.

Gearing

The steepest ramp governs your gearing choice, and it sits well into double-digit gradients. Do not turn up on a standard chainset. Run a compact (50/34) or sub-compact chainset paired with a wide-range cassette — a 34×32 or 34×34 low gear gives you room to spin the steep pitches instead of grinding them. On a climb this long, protecting your cadence early keeps your legs alive for the repeated efforts later. Check your setup before the ride, not at the bottom of the first steep ramp.

Summary

• Length: 17.7 km
• Average gradient: 5.8%
• Net elevation gain: 1,027 m
• Total ascent: 1,569 m
• Category: 1

Znachsattel is a Cat-1 climb that asks more of you than its average gradient advertises. Ride it to even effort, gear for the steep ramps, and account for all 1,569 m of ascent — the extra 542 m is where this climb is won or lost.
