Termas de Chillán is a climb of 49.3 kilometers (hors catégorie). Termas de Chillán tops out at 1,706 m above sea level. It is located in Las Vertientes, Región de Ñuble, Chile. The average gradient is 3.0% with a maximum of 14.8%. The climb has 1479 meters of elevation gain.
Difficulty breakdown: A long climb (49.3 km) but with a moderate average gradient of 3%. The difficulty lies in its irregularity: several sections at 4-6% between km 7 and 14, then a false flat descending (km 19 to 22) before a very testing finish. The last 3 km hit steep gradients (8% to 12%), which makes them the crux of the climb.
Pacing advice:
1. Steady rhythm in the first half: The gradient is generally easy over the first 18 km. Don't go too hard early on and save your legs for the end.
2. Prepare for the hard finish: Keep some energy in reserve for the last 5 km (from km 44), where the gradient goes above 8%. This is where the climb is won or lost.
3. Make use of the recovery sections: The sections with easy or negative gradient (km 19-22) are good opportunities to recover and refuel without losing speed.
