Rotes Kreuz

Overview

Rotes Kreuz is a Category 2 climb in Germany that runs for 7.7 km. It starts at 301 m and tops out at 700 m, giving a net elevation gain of 399 m from base to summit. On paper that reads as a steady mid-length ascent at a moderate average gradient, the kind of effort most fit riders can settle into and hold.

The number that reshapes the ride is total ascent: 524 m against 399 m of net gain. That 125 m gap is climbing you do that the summit elevation never credits you for — the road gives back altitude in dips and false flats before demanding it again. On an undulating profile like this, the average gradient understates the work. You will pay for those descents twice, and the repeated re-accelerations cost more than a single uniform grade of the same length.

How the Gradient Unfolds

The 5.21% average is a blend, not a description of any single stretch. With 125 m of hidden re-climbing folded in, the road clearly rolls: sections that ease off or tip slightly downhill, then reload. The steepest ramp bites at 12.42% — more than double the average — so there are pitches where you are well into a low gear while other parts barely register as climbing.

• Flatter and recovery sections where the grade drops well below 5% or tips downhill
• Repeated short climbs stacked back to back rather than one continuous wall
• A steepest ramp at 12.42% that forces a gear change and a brief hard effort

Pacing Notes

On a smooth climb you can chase even speed. Here, don't. The undulation makes even-speed pacing a trap: holding a target km/h over the 12.42% ramp would spike you far above your sustainable power output and leave you cooked before the summit. Ride even effort instead. Let your speed rise on the flatter sections and fall on the ramps while your power stays roughly constant. Resist the urge to hammer the dips to "make up time" — that surging is exactly what the 125 m of extra ascent punishes. Know your ceiling before you start; the FTP estimator gives you the number to hold across all 7.7 km.

Gearing

Gearing is set by the steepest gradient, not the average. At 12.42%, on tired legs late in a 7.7 km climb, you want spin in reserve. Run a compact (50/34) or sub-compact chainset paired with a wide-range cassette — something like 34×32 or 34×34 — so you can hold cadence on the ramp without grinding. Check your setup before the ride: confirm the chain reaches the largest sprocket cleanly and shifts under load. Discovering you're a gear short mid-ramp is a bad place to find out.

Summary

• Length: 7.7 km
• Average gradient: 5.21%
• Maximum gradient: 12.42%
• Net elevation gain: 399 m
• Total ascent: 524 m
• Category: 2

Rotes Kreuz is a moderate climb with a rolling character. The 399 m net gain undersells it — the 524 m of total ascent is what your legs will feel. Pace it by effort, gear it for the 12.42% ramp, and the undulation works with you instead of against you.
