Durchspring

Overview

Durchspring is a Category 1 climb in Austria that runs 9.6 km from a valley start at 593 m to a summit at 1,312 m. On paper that is a net elevation gain of 719 m across the ascent, with an average gradient of 7.48% — squarely in the range that separates a serious climb from a hard effort you can bluff your way through.

But the net gain only tells part of the story. Durchspring records 1,200 m of total ascent against that 719 m net gain, a difference of 481 m. That gap is undulation: the road repeatedly rises and falls rather than climbing in one clean line. Every metre you lose to a dip is a metre you have to reclaim, and those hidden re-climbs are what turn a 719 m profile into a 1,200 m day in the legs.

How the Gradient Unfolds

An average of 7.48% is deceptive on a climb this lumpy. The undulation means the average is dragged down by descents and flat sections, which implies the working pitches are meaningfully steeper than 7.48% — and the maximum touches 30.19%. Expect the effort to arrive in bursts rather than as a steady drag.

• Flatter and recovery sections where the road eases or briefly drops, tempting you to over-spend
• Repeated short climbs that reset your rhythm again and again across the 9.6 km
• A steepest ramp near 30% that will spike your power well above any sustainable number

Pacing Notes

On a smooth climb you can ride to a steady wattage and let speed take care of itself. Durchspring's undulation breaks that model. Chasing even speed here means burying yourself on every ramp and coasting the dips — a recipe for blowing up. Instead, pace to even effort: hold a target close to your sustainable power output, accept that speed will swing wildly, and resist the urge to match a number over the 30% pitches where a short surge is unavoidable. If you do not know your ceiling, run the FTP estimator before you go, then ride the climb at or just under it.

Gearing

The steepest gradient governs your gearing, and a 30.19% ramp is unforgiving. A standard road setup will grind you to a stall. Fit a compact (34-tooth inner) or sub-compact chainset paired with a wide-range cassette — a 34×32 at minimum, and 34×34 if your derailleur allows it — so you keep a spinnable cadence when the road stands up. Check your chainset and cassette before the ride; discovering you are over-geared halfway up a 30% wall is not a mistake you recover from.

Summary

• Length: 9.6 km
• Average gradient: 7.48%
• Maximum gradient: 30.19%
• Net elevation gain: 719 m
• Total ascent: 1,200 m
• Category: 1

Durchspring is a Category 1 climb that earns its rating through undulation, not just distance. Pace to effort, gear for the steepest ramp, and treat the 481 m of hidden re-climbing as the real challenge — not the number on the summit sign.
