Difficulty analysis: The Oštrelj covers 14.6 km for 573 m of elevation gain, with an average gradient of 3.9%, which makes it a Category 1 climb that is demanding but steady. The first two kilometers, at 5% then 6%, and the stretch from km 2.0 to km 3.0 at 6%, call for a very strong start that puts your legs to the test early. The rest alternates between easier-rolling sections, notably from km 5.0 to km 9.0 where the gradient drops to 1% or 2%, and 5% ramps between kilometers 9.0 and 11.0. The finish, with 5% from km 13.0 to km 14.0 then 6% to the line, requires saving something in the tank.
Pacing advice:
1. Manage the start. Tackle the first three kilometers, at gradients of 5 to 6%, with a controlled effort so you don't blow up before the middle section.
2. Make the most of the false flats. Between kilometers 5.0 and 9.0, where the gradient eases to 1% or 2%, recover, drink and eat, then settle back into a steady rhythm.
3. Pace the final kilometers. From km 13.0 to the finish, the 5% then 6% gradients demand that you keep your gear and mental strength to finish strong.
