Ugeon Pass

Ugeon Pass cycling climb profile

Ugeon Pass is an HC climb in CH that asks a very simple question for a long time: can you keep producing controlled climbing power when the road rarely gives much back?

The headline numbers are severe. The climb runs for 18 km, starts at 381 m, and tops out at 2060 m. That means 1679 m of net elevation gain, with an average gradient of 9.33%. The maximum gradient reaches 19.77%, which changes how the whole climb should be approached. This is not just a long steady tempo ascent. It is a climb where the baseline is already hard, and the steepest pitches can punish any early overreach.

How the gradient unfolds

With only the climb-wide profile available, the most important reading is the relationship between length, average gradient, and maximum gradient. An 18 km ascent at 9.33% leaves very little margin for recovery. If the road eases at any point, the mathematics of the climb mean those easier moments are offset elsewhere by gradients above the average, with the steepest sections reaching nearly 20%.

That makes Ugeon Pass feel different from a climb where the difficulty is concentrated into one decisive wall. Here, the main stress is accumulated. The lower slopes begin from 381 m, so the climb immediately commits you to a large vertical gain. By the time the road approaches the summit elevation of 2060 m, the fatigue cost is not just muscular. It is also pacing debt: every surge, every over-geared ramp, and every effort above threshold has to be carried through the remaining ascent.

Pacing strategy

The correct approach is conservative early, disciplined through the middle, and only aggressive once the summit is genuinely within reach. On a climb this long and this steep, riding by feel alone can be misleading because a gradient around the average already feels urgent. If you ride the opening as if 9.33% is the hard part, the 19.77% maximum ramps will become much more expensive later.

Use /glossary/ftp as the anchor. For most riders, the target should be a sustainable climbing effort below the point where breathing and cadence begin to drift. The steep ramps are not places to prove strength. They are places to limit losses. Let power rise if it has to, but avoid turning every pitch into a seated strength interval.

Gearing and technique

Choose gearing for the maximum gradient, not the average gradient. The average of 9.33% already demands a compact, efficient cadence for most riders, but the 19.77% ramps are where inadequate gearing becomes costly. If the lowest gear forces you into grinding too early, the climb will load the legs long before the summit.

Practical priorities:

• Start with a cadence you can keep under control on sustained gradients near the average
• Keep one gear in reserve whenever the road allows it
• On the steepest ramps, stay seated if traction and cadence allow, but do not hesitate to stand briefly to reset the legs
• Fuel before the effort feels critical, because an 18 km HC climb gives little room to recover from a missed intake

Ugeon Pass is best treated as a durability test, not a single decisive attack. The numbers reward patience: hold the effort together, gear for the worst pitches, and let the climb come back to you rather than trying to force it from the bottom.
