Difficulty breakdown: At 9.7 km with 543 m of elevation gain and an average gradient of 5.6%, the 우현령 climb is rated beyond category and demands a sustained effort from start to finish. The profile is uneven: after a 4% start on KM 0.0-0.5, the 6% sections (KM 3.0-3.5 and KM 5.0-5.5) alternate with 2% flat stretches (KM 3.5-4.0 and KM 5.5-6.0), so it's hard to settle into a steady rhythm. The hardest part comes between KM 6.5-7.0 (6%) and KM 7.0-7.5, where the gradient hits 7% over 510 m, before an easier 4% section (KM 7.5-8.0). The finale, at 5% over KM 9.5-9.7, is still tough after the 2% respite on KM 9.0-9.5.
Tips for managing your effort:
1. Pacing the start: Don't go out too hard on the 4% KM 0.0-0.5 section, because there's still a lot of climbing left to get through.
2. Making the most of the flats: Use the 2% sections (KM 3.5-4.0, KM 5.5-6.0 and KM 9.0-9.5) to recover and top up your energy before the 6% and 7% ramps.
3. Dosing your effort in the final part: On the 7% KM 7.0-7.5 section, stay seated and keep a smooth cadence, then save some legs for the 5% KM 9.5-9.7 section.
