Gradient profile
Overview
Črnivec Pass is a Category 2 climb in Slovenia, running 8 km from the valley to the pass road summit. It gains 494 m net across that distance, starting at 437 m and topping out at 931 m. At an average gradient of 6.14%, it sits in the range where a climb is long enough to demand real pacing discipline but short enough that a strong effort pays off.
The number to watch is the gap between net elevation gain and total ascent. You gain 494 m in altitude, but you actually climb 751 m — meaning roughly 257 m of that gain is repeated, given back on descents and false flats before you claw it back. That undulation makes the ride harder than the average gradient suggests: you never settle into a single rhythm, and every dip forces you to accelerate back up to speed on the next rise.
How the Gradient Unfolds
The 6.14% average is a blend, not a constant. Because 257 m of the climbing is undulation, stretches of easy or descending road sit alongside pitches well above the mean. Expect the steepest ramp to hit hard where the road pinches — that is where the effort is decided, not on the shallow sections.
- Flatter and recovery sections where the road dips or runs near-level between rises
- Repeated short climbs that force you to re-accelerate again and again
- A steep ramp that spikes well above the 6.14% average and sets the gearing you need
Pacing Notes
On a steady climb you can hold even effort and let speed float with the gradient. Črnivec's undulation complicates that. On the descents and false flats, do not chase speed — soft-pedal, recover, and save your matches for the rises. Anchor your climbing to your sustainable power output rather than a target speed, because the rollers will wreck any attempt to hold a fixed pace.
Know your ceiling before you start. Run the FTP estimator to set a realistic number, then cap your surges on the steep pitches a little above it and let the flatter parts bring your average back down.
Gearing
The steepest ramp governs your setup, not the average. For a pitch this steep on tired legs late in an 8 km climb, run a compact (50/34) or sub-compact chainset paired with a wide-range cassette. A 34×32 gives you room; a 34×34 gives you a genuine bailout gear for the sharpest ramp. Spinning a low gear beats grinding a big one and blowing up mid-climb. Check your chainring and cassette combination before the ride — swapping a cassette in the car park is not a plan.
Summary
- Length: 8 km
- Average gradient: 6.14%
- Maximum gradient: 20.34%
- Net elevation gain: 494 m
- Total ascent: 751 m
- Category: 2
Črnivec Pass rewards riders who respect its undulation. Pace to power, gear for the steepest ramp, and treat the recovery sections as recovery — do that, and the 494 m to the summit comes without a blow-up.
