Dizin

Overview

Dizin is a short, high-altitude test that packs a genuine punch into its 3.7 km. From the very first metre it climbs at altitude, starting at 2563 m and topping out at 2789 m for a net elevation gain of 226 m. Add in the rolling pitches and dips along the way and the total ascent comes to 235 m. The average gradient of 6.16% marks this as a steady, honest grind rather than a wall, but the thin air is the real story here: every watt costs more than it would at sea level. It carries a category 3 rating, placing it below the category 1 and 2 monsters yet well above a mere warm-up.

How the Gradient Unfolds

Over 3.7 km the climb averages 6.16%, and that number does most of the talking. This is a consistent gradient, the kind you can settle into and hold. The steepest ramp reaches 10.76% max, so there is a moment where the slope nearly doubles the average and demands a brief change of rhythm. Because the total ascent (235 m) slightly exceeds the net gain (226 m), you can expect a small amount of false flat or shallow descent breaking up the effort — roughly 9 m of extra up-and-down folded into the profile. Read the road ahead: hold power through the steeper section near that 10.76% pitch, then recover on the gentler stretches before the summit at 2789 m.

Pacing Notes

At 3.7 km this is an effort you can push hard, but altitude flips the usual maths. Aim to ride the bulk of the climb just below your threshold and save headroom for the 10.76% ramp. Your FTP is the anchor for pacing here: target the climb at a percentage of it that you can sustain for the full 3.7 km without blowing up on the steep pitch. If you are unsure of your number, run a quick check with the FTP estimator before you commit to a target. Above 2500 m, expect your sustainable power to sit lower than your sea-level figure, so pace conservatively early and trust that the average gradient of 6.16% rewards a steady tempo over heroics.

Gearing

For a 3.7 km climb at 6.16% with a 10.76% max, a compact setup gives you the range to stay seated and spinning. A 34×32 will cover most of the climb comfortably, letting you turn a smooth cadence across the sustained gradient. But the 10.76% ramp — made harder by the altitude — is exactly where a bailout gear earns its keep, so a 34×34 is the safer choice if you would rather protect your legs than grind. Given the thin air at 2563 m and above, err toward the easier ratio.

Summary

Dizin is a compact, high-altitude category 3 climb: 3.7 km of steady 6.16% grinding with a 10.76% sting, all played out between 2563 m and 2789 m. Pace it below threshold, respect the altitude, and gear low enough to keep spinning.
