Difficulty analysis: With 4.6 km at an average gradient of 8.1% and 372 m of elevation gain, the climb of 海心田 from Beiying is a demanding first-category col. The first two kilometres at 4% are rolling, then a short descent at -3% (between 1 and 1.5 km) comes before the real start of the difficulty. Between 1.5 and 2 km, the gradient ramps up to 12%, and the 3 to 3.5 km section peaks at 15%, making it the hardest part. The finale stays tough with 10% between 3.5 and 4 km, then 8% all the way to the top.
Tips for managing your effort:
1. Save some in the tank early on: make the most of the first two kilometres at 4% to find a steady rhythm and avoid burning your matches too soon.
2. Prepare for the 15% wall: shift to an easier gear before the 3rd km, stay seated, and keep a smooth, light cadence so you don't go into the red.
3. Recover on the 5% section: between 2 and 2.5 km, use the gentler gradient to take on nutrition and get your legs ready before the 10% section that follows.
