Urdenfürggli

Urdenfürggli cycling climb profile

Urdenfürggli is a major Swiss HC climb by any practical measure: 20.6 km long, 2016 m of net elevation gain, and an average gradient of 9.77 percent from a start elevation of 592 m to a summit elevation of 2608 m. Those numbers tell you the main story before the road is even split into sectors. This is not a climb where the average is softened by long flat sections. An average just under 10 percent across more than 20 km means the difficulty is persistent, and the cost of riding above threshold early will compound hard.

The maximum gradient of 19.8 percent is the number that should shape your gearing choice, but the average gradient is the number that should shape your pacing. The climb is long enough to demand endurance pacing, yet steep enough that low cadence grinding can become the limiting factor well before the summit.

How the gradient unfolds

With only the core profile stats available, the safest way to read Urdenfürggli is as a sustained high-gradient ascent rather than a climb defined by one isolated ramp. Over 20.6 km, an average of 9.77 percent means the road is continually asking for torque. Even if the steepest 19.8 percent pitches are short, they sit inside an already demanding climb, so they are not free surges. They arrive when the rider is likely already carrying muscular fatigue.

That matters because a climb like this punishes variable pacing. On shallower climbs, brief accelerations can be absorbed aerodynamically or through momentum. Here, speed is low and gravity dominates. Every time you go too hard on a steep section, the repayment comes quickly: cadence drops, breathing rises, and the next section feels steeper than it is.

Pacing strategy

Treat the lower portion as controlled work, not as a place to bank time. The combination of 20.6 km and 2016 m of net gain makes the climb closer to a full endurance test than a single maximal effort. If you ride by power, anchor the first part below the effort you think you can hold for the whole climb, especially if your /glossary/ftp is set from flatter terrain or shorter efforts.

A good practical rule is to let cadence and breathing cap the effort on the steepest ramps. When the gradient approaches the maximum of 19.8 percent, the goal is not to maintain the same speed. The goal is to keep the pedals turning without creating a spike that damages the next several kilometres. On a climb averaging 9.77 percent, the hard sections are not interruptions. They are part of the main workload.

Gearing notes

Gear for the maximum gradient, not the average. A setup that feels comfortable at 9 or 10 percent may become marginal when the road rises toward 19.8 percent, especially late in the climb. Most riders will want a bailout gear that allows seated climbing at a sustainable cadence rather than being forced into repeated standing efforts.

Standing can help clear the steepest pitches, but if it becomes the default response, the gearing is probably too ambitious. Urdenfürggli rewards restraint: small gears, smooth torque, and a pace that still feels repeatable well past halfway. The summit elevation of 2608 m adds another reason to avoid early overreach, because the climb finishes high after a very large vertical gain.

What it asks of the rider

Urdenfürggli is not a climb to bluff. Its difficulty comes from the alignment of length, average gradient, maximum gradient, and elevation gain. The profile demands a low-ego ride: conserve early, protect cadence, and let the steepest sections pass without turning them into attacks on yourself.
