Radstädter Tauern Pass

Overview

The Radstädter Tauern Pass is a long, sustained category 1 climb that trades brutality for patience. Over 18.1 km it lifts you from a start elevation of 839 m to a summit at 1744 m, a net gain of 905 m. The headline average gradient of 5% sounds gentle, and for long stretches it is — but this is a climb measured in duration rather than ferocity. At nearly 18 km with a total ascent of 890 m of pedaling, it demands the kind of controlled, metronomic effort that rewards riders who resist the temptation to chase early.

How the Gradient Unfolds

A 5% average across 18.1 km never tells the full story, and here the number hides real texture. Expect long ramps that sit close to the mean, broken by shallower recovery drags and the occasional sharper kick. The steepest recorded pitch hits 11.23% — more than double the average — so the climb is not perfectly uniform. Those steeper sections are where the difference between the 905 m net gain and the 890 m of measured ascent becomes tangible: brief flatter or descending respites shave a little off the pure vertical, meaning your legs get short windows to reset before the road tilts up again. Read the road, and you can spend those flatter meters gathering yourself for the ramps rather than burning matches on them.

Pacing Notes

On a climb this long, pacing is everything. Aim to settle just below your threshold and hold it — a climb of 18.1 km is far too long to ride at your limit from the base. A good target is a steady percentage of your FTP: most riders will want to sit comfortably under it for the bulk of the ascent, keeping something in reserve for the 11.23% pitches where power naturally spikes. If you are unsure of your number, run through the FTP estimator before you go so your pacing is anchored to real data rather than feel. The cardinal error here is going out hard on the early ramps; with 905 m still to gain, an over-cooked first third turns the final kilometers into damage control.

Gearing

For an 18.1 km climb at 5% with pitches to 11.23%, err toward more range than you think you need — fatigue at the top of a long climb makes a spinning cadence worth far more than raw grunt. A compact chainring paired with a wide-range cassette is ideal. A 34×32 will handle the sustained 5% sections and most riders well, keeping cadence high without over-gearing. But if you carry any load, ride tired, or simply want insurance on the steeper 11.23% ramps, step up to a 34×34. That extra sprocket is cheap security on a climb where the summit sits 905 m above where you started.

Summary

The Radstädter Tauern Pass is a classic long-and-steady category 1 test: 18.1 km, a 5% average, and just enough steep punctuation to keep you honest. Pace it patiently, gear it generously, and the 905 m of net gain becomes a rhythm rather than a wall.
