Toblinger Riedl - Forcella di Toblin

Overview

The Toblinger Riedl - Forcella di Toblin is one of those climbs that leaves little room for negotiation. Over just 6.7 km it gains 937 m from a start elevation of 1416 m to a summit at 2353 m, holding a punishing average gradient of 13.94%. That number alone puts it in rare company, and the classification confirms it: this is an HC (hors catégorie) climb, the hardest rating on the scale. There is no gentle build-up here and no long false flat to hide behind. The road tips up early and stays steep, which is exactly why the average sits so high across the full distance.

How the Gradient Unfolds

To understand this climb you have to think in terms of sustained load rather than isolated ramps. A 13.94% average over 6.7 km means the road almost never eases enough to let you recover in the saddle. The defining feature is the max gradient of 33.47% — a wall so severe that on many bikes it approaches the limit of what is rideable while seated. With net elevation gain of 937 m and total ascent of 901 m, the profile is relentlessly upward with very little give-back; the small difference between those two figures tells you there are almost no descending or flat sections to interrupt the climbing. Expect the steepest pitches to force you out of the saddle repeatedly, with the gradient rarely dropping into anything you would call comfortable.

Pacing Notes

On a climb this steep, pacing is survival. Because the gradient averages 13.94% and spikes to 33.47%, you cannot simply hold a steady wattage — the terrain will drag your power far above threshold on the ramps whether you like it or not. The smart approach is to ride the shallower sections conservatively so you bank a little headroom for the walls. Knowing your FTP is essential here, because your sustainable effort defines how far above it you can afford to surge on the 33.47% pitches before you blow. If you are not sure of your current number, run it through the FTP estimator before you plan your assault. Aim to crest each steep ramp still able to breathe, then use the marginally easier grades to bring your heart rate back down.

Gearing

Do not underestimate what 13.94% average and 33.47% max demand from your drivetrain. This is not a climb for a road-race setup. At minimum, run a compact chainring paired with a wide-range cassette — a 34×32 is the sensible floor, and even that will feel tall on the steepest ramps. For most riders a 34×34 is the wiser choice, giving you an extra cog of relief to keep your cadence out of the grinding zone where knees and back suffer. If your frame and derailleur can accommodate more range still, take it. Over 6.7 km with 937 m of gain, easier gearing is not a weakness — it is the difference between riding the summit and walking to it.

Summary

The Toblinger Riedl - Forcella di Toblin is a short, savage HC test that rewards respect and punishes bravado. Prepare your legs, dial in your gearing, and pace the shallower grades to survive the 33.47% walls.
