Eiserne Hand

Overview

Eiserne Hand is a Category 3 climb in Germany, running 6.5 km from base to summit. It starts at 149 m of elevation and tops out at 437 m, for a net elevation gain of 288 m. On paper that reads as a steady, mid-length effort — long enough to matter, short enough to hold a rhythm — with an average gradient of 4.41%.

The net figure only tells part of the story. Total ascent over the climb is 331 m against a net gain of 288 m, which means roughly 43 m of the road tips back downhill along the way. That undulation is the defining trait here: you are not grinding one continuous slope but repeatedly gaining, giving a little back, and climbing again. Every metre lost to a dip has to be re-earned, so the actual work is higher than the net gain suggests, and momentum is easily broken if you pace it wrong.

How the Gradient Unfolds

The 4.41% average is a blend, not a constant. With a maximum gradient of 8.54%, the steepest ramp is nearly double the average, so the road clearly stacks its difficulty into short, sharp sections separated by easier ground. Expect the effort to arrive in pulses rather than as one sustained wall.

• Flatter and recovery sections where the road eases or briefly descends, letting you spin and reset.
• Repeated short climbs that build gain, then hand a little back before the next rise.
• A steepest ramp around 8.54% — the pitch that decides your gear choice and where a mispaced effort bites hardest.

Pacing Notes

On an undulating climb like this, even-effort pacing beats even-speed pacing. Chasing a fixed speed forces you to surge over every steep pitch and coast the dips, spiking and stalling your output. Instead, hold a steady sustainable power output and let your speed rise and fall with the road: faster on the flatter sections, slower on the 8.54% ramp.

Know your ceiling before you start. Use the FTP estimator to set a target you can hold across the full 6.5 km, then ride just under it on the ramps so you have something left for the next rise rather than blowing up on the first steep pitch.

Gearing

The steepest gradient governs your setup. At 8.54% you want a compact or sub-compact chainset paired with a wide-range cassette — a 34×32 or 34×34 gives you a low enough bailout to spin the steep ramps at a comfortable cadence instead of grinding. That protects your legs across the repeated climbs so the undulation doesn't drain you. Check your chainset and cassette before the ride; the base of a climb is the wrong place to discover you're over-geared.

Summary

• Length: 6.5 km
• Average gradient: 4.41%
• Maximum gradient: 8.54%
• Net elevation gain: 288 m
• Total ascent: 331 m
• Category: 3

Eiserne Hand is a manageable Category 3 effort whose modest average masks steep ramps and roughly 43 m of give-back terrain. Pace it by effort, gear it for the 8.54% pitch, and the undulation becomes rhythm rather than a repeated punch.
