Kubalonka Pass

Overview

Kubalonka Pass is a category 3 climb that stretches 8.2 km from a start elevation of 430 m up to a summit of 760 m. That gives it a net elevation gain of 330 m over an average gradient of 4.01% — a steady, moderate haul rather than a wall. With a total ascent of 317 m recorded along the way, the road climbs almost continuously, but never so severely that it forces you out of the saddle for long. This is a climb you settle into: long enough to matter, gentle enough to reward good pacing over raw explosiveness.

How the Gradient Unfolds

The headline number is the 4.01% average, but averages flatten out the story. The steepest recorded pitch reaches 9.59%, more than double the mean, which tells you the climb is not uniform. Expect the ramp to ease and stiffen in waves rather than hold a single grade. The gap between the 317 m total ascent and the 330 m net gain is small, confirming there is very little downhill or false flat to break the rhythm — nearly every metre of the 8.2 km trends upward. Save something for the sharper ramps, because a 9.59% kick after several kilometres of climbing bites harder than it would fresh.

Pacing Notes

On a climb this length, discipline beats bravado. Aim to hold a tempo effort a touch below your threshold on the shallower sections and let your power drift up only when the gradient rears toward that 9.59% maximum. If you know your FTP, target roughly 85 to 90 percent of it as a sustainable ceiling for the 8.2 km — high enough to be quick, low enough to survive the steep pitches. Not sure of your number? Run the numbers through our FTP estimator before you commit to a target watts figure. The worst mistake here is going too hard early on the 4.01% opening and paying for it when the road tilts up.

Gearing

At 4.01% average this is not a climb that demands the deepest gears, but the 9.59% max is steep enough that most riders will want a bailout cog. A compact 34-tooth chainring paired with a 34×32 low gear covers the majority of the climb comfortably, letting you spin the steady sections and grind the ramps without cross-chaining into trouble. If you carry extra weight, ride tired, or simply prefer a higher cadence, step up to 34×34 for a little more relief on the harshest 9.59% pitch. Either setup keeps your cadence smooth across the full 8.2 km.

Summary

Kubalonka Pass is an honest category 3 test: 8.2 km of near-continuous climbing at a manageable 4.01% average, spiked by a 9.59% maximum, delivering you 330 m higher than where you started. Pace it patiently, gear it sensibly, and it rewards you rather than breaks you.
