Difficulty breakdown: This 21.9 km HC climb is a demanding test because of its length and its serious 1603m of elevation gain. Although the 7% average gradient is typical for a big mountain pass, the real difficulty lies in the uneven profile. The gradient keeps changing, with several stretches at 7-8% (especially between km 6-9 and km 19-20) that break your rhythm, followed by short easier sections (km 12-16) that offer very little recovery.
Tips for managing the effort:
1. Settle into a steady rhythm from the start. The first few km are easy (1%-5%). Resist the temptation to go out too hard, and save your legs for the nasty 8% sections.
2. Use the easier sections (km 12 to 16, gradients of 2% to 4%) to recover actively. Keep a high cadence without mashing the gear, rather than using them to attack.
3. Prepare for the last two km. The gradient drops to 3%. Get ready mentally and physically for that "flattening out" at the end so you can hold your power all the way to the summit.
Cyclists describe a climb that has to be earned, with a steady, demanding gradient that puts your legs to the test from the very first switchbacks. The difficulty is real, but that's exactly what makes reaching the summit so rewarding.
The ride comes with a sometimes tricky coexistence with traffic. Riders don't hold back when they talk about trucks, cars and especially motorbikes that pass uncomfortably close, creating noise and a certain amount of nerves. This is a very busy road, not a quiet, isolated climb.
Still, the scenery is often cited as the ultimate reward. Riders report spectacular views over the valleys and, if the weather cooperates, the unique feeling of riding above the clouds. These moments of pure beauty contrast sharply with the chaos of the road and stay with you long after the ride.
The mood at the top is described as a mix of relief and shared pride. Riders highlight the camaraderie between cyclists who have just survived the same effort, swapping grins and words of encouragement in front of the col sign.
