Tips

Difficulty breakdown: At 20.6 km for 1031 m of elevation gain and an average gradient of 5%, Gunung Seruk from Mentaraman is a HC climb of serious length. The first half is fairly rolling, with gradients between 1% and 3% from km 0 to 8. Things ramp up noticeably after km 8, with sections at 7%, 8% and 9% between km 13 and 16, then again between km 18 and 20, which makes the finish particularly punishing.

Pacing tips:

1. Pace yourself from the bottom. The first 8 km, at 1-3%, are the time to settle into a steady rhythm and save some legs for what's coming.

2. Prepare for the 7-9% sections. Between km 13 and 16, drop into an easy enough gear and stay seated to keep your cadence smooth.

3. Manage the final part. Km 18 to 20 sits at 8 to 9%: keep drinking and fuelling regularly before you tackle that last push.
