Difficulty breakdown: With 22.4 km, 847 m of elevation gain and an average gradient of 3.8%, the Thaga Pass is rated HC mainly for its length rather than the steepness of its slopes. These remain moderate, between 1% and 5%, but they are almost continuous over more than 20 km, which wears your legs down gradually. The toughest sections are from km 2 to km 5 (5%), then km 12-13 and 14-15 (5%). The main challenge is therefore managing your effort over the duration.
Pacing tips:
1. Start conservatively. In the first kilometers at 4% (0-2 km), spin an easy cadence so you don't burn your matches before the 5% section from km 2 to 5.
2. Recover on the flatter stretches. Make the most of the gentler sections, like km 16-17 at 2% and especially 19-20 at 1%, to pick up the cadence again and catch your breath.
3. Save something for the finale. After km 20, the 3% slopes from km 20-22 still demand steady pedalling, so save your legs for those final kilometers.
