Difficulty breakdown: With 22.8 km for 1675 m of elevation gain and an average gradient of 7.3%, the climb of Laoshan (老山) from Mangun is beyond category. The first three kilometres are steady at 6%, then the route alternates between rolling sections (1 to 2% from km 3 to km 6, 3% from km 7 to km 10) and punchy stretches at 5 to 7%. The final part is the hardest, with km 18 to 22.8 at 7%, 7%, 9%, 5% and then 9%, after a long stretch that's already taxing. All of this adds up to a very demanding test of endurance.
Tips for riding it:
1. Pace the start at 6% Take the first three kilometres at a measured pace so you don't burn through your reserves before the middle section.
2. Recover on the rolling sections Use the almost flat km 3 to 6, and the descent between km 8 and 9, to drink, eat and get your legs turning over again.
3. Save something for the finale Stay in a suitable gear and keep a steady cadence on the 7% stretches between km 18 and 20, so you reach km 20 to 22.8 at 9% with your legs still in good shape.
