U Barborky

U Barborky cycling climb profile

U Barborky is the kind of climb that looks manageable on average and becomes selective through duration. At 25.5 km and 3.76%, it is not defined by a single wall or a consistently severe gradient. The challenge is that it keeps asking for pressure on the pedals for a long time while gaining close to a thousand metres from start to summit.

The climb starts at 374 m and tops out at 1332 m, with 958 m of net elevation gain. That tells you the basic shape: this is a sustained uphill road rather than a short punch. The category 2 rating fits that profile. It is long enough that poor pacing early will show up later, especially if you ride the opening kilometres as though the average gradient makes it easy.

How the gradient rides

The headline average of 3.76% is only part of the story. A climb this long at that average can feel deceptively gentle when the road eases, but the listed maximum gradient of 13.99% shows that U Barborky is not a smooth metronomic drag from bottom to top.

That contrast matters. The average suggests plenty of time spent on moderate gradients, but the maximum gradient means there are steeper sections capable of forcing a shift in cadence, power, and breathing. In practice, the danger is not the steepest ramp by itself. It is arriving at that ramp after already committing too much energy across the long lower and middle portions of the climb.

Because the total ascent is listed at 944 m and the net elevation gain at 958 m, the data should be read as a broad climbing profile rather than a micro-segment map. The useful takeaway is still clear: this is a long uphill effort with meaningful vertical gain and short enough steepness to disrupt rhythm.

Pacing strategy

Treat U Barborky as an endurance climb first and a steep-ramp climb second. The average gradient can tempt riders into pushing above sustainable power because the road may not feel hard enough early on. That is the mistake. Over 25.5 km, small overages accumulate, and the 13.99% maximum gradient leaves little room to hide if fatigue is already building.

A sensible approach is to ride the early part just under your target climbing effort, settle into a controlled cadence, and save the harder work for the steepest pitches and the final portion toward 1332 m. If riding by power, anchor the effort around a level you can repeat without drifting above threshold too often. For more on setting that ceiling, see /glossary/ftp.

Gearing notes

Use gearing that respects the maximum gradient, not just the average. A setup chosen only for 3.76% may feel fine for much of the climb but leave you grinding when the road touches its steepest ramps. A compact or similarly forgiving climbing gear is the safer choice for most riders, especially if the climb comes late in a ride.

The best gear here is one that lets you stay seated, keep cadence from collapsing, and absorb changes in gradient without repeated surges. U Barborky rewards patience: ride the average too hard and the steep sections become expensive; ride the average calmly and the climb becomes a long, controlled test rather than a slow fade.
