Difficulty analysis: This 12.9 km climb, with 646 m of elevation gain and an average gradient of 5%, earns its HC rating through its length and an effort that almost never lets up. The opening is the hardest part: the first three kilometres run at 6%, 6% and then 7%. The stretch from km 3 to 4, at just 1%, gives you a real breather before the 4 to 5% gradients return all the way to km 11. The finale, at 6% over the last 0.9 km, closes out a very steady climb.
Tips for pacing yourself:
1. Don't go out too hard: in the early kilometres, where the gradient ramps up to 6% then 7% between km 2 and km 3, it's better to keep a controlled cadence and save your legs.
2. Make the most of the flat section: the km 3 to 4 stretch at 1% is the perfect chance to drink, fuel up and find an efficient rhythm again before what's coming.
3. Save something for the finish: hold a steady effort from km 4 to km 11, then keep some in the tank for the 6% of the final section, from km 12 to 12.9.
