Hals Pass

Overview

Hals Pass is a Category 3 climb in Austria that covers 5 km from base to summit, rising 235 m in net elevation gain with a total ascent of 338 m. That gap between net gain and total ascent signals the road doesn't simply roll upward in a straight line — expect some undulation and at least one section where you briefly give back elevation before climbing again.

The average gradient of 4.68% keeps this climb well within manageable territory for most trained riders, but the maximum gradient of 12.77% means there is at least one sustained ramp that demands respect. If you arrive at that steep pitch already carrying fatigue from earlier undulations, it can catch you out.

How the Gradient Unfolds

With a 235 m net gain over 5 km averaging 4.68%, the arithmetic is straightforward — but the 338 m of total ascent tells a more honest story. The road accumulates roughly 100 m more climbing than the summit-to-start difference accounts for, so pacing purely to the average gradient will leave you underprepared for the harder sections.

The 12.77% maximum is the number to keep in mind. On a climb of this length, a pitch that steep is likely concentrated in one or two distinct ramps rather than spread evenly. Riders who push hard on the gentler early slopes risk blowing up when the gradient kicks sharply upward.

Gradient Summary

• Length: 5 km
• Average gradient: 4.68%
• Maximum gradient: 12.77%
• Net elevation gain: 235 m
• Total ascent: 338 m
• Category: 3

Pacing Notes

For a climb in this length and category, effort management is straightforward in principle but easy to mishandle. The moderate average invites riders to push from the bottom, but that 12.77% ramp will expose anyone who has gone too deep too soon.

A target effort just below threshold — roughly 90–95% of FTP — is a reasonable starting point for riders treating this as a training climb or a race segment. If you're unsure of your current FTP, use the FTP estimator before dialling in your power targets.

Hold something back in the opening kilometre. If the road undulates and gives back height before the final push, use any descent or flat to recover rather than surge. Arrive at the steepest pitch with legs that still have a gear to give.

Gearing Notes

At 4.68% average, a compact chainset (50/34) paired with an 11-32 or 11-34 cassette covers this climb comfortably for most riders. The 12.77% maximum will push lighter or less trained riders toward the smaller end of that range. Riders on a standard 53/39 setup should confirm they have enough cassette range to spin through the steepest ramp without grinding to a halt.

Heavier riders or those coming to Hals Pass at the end of a long day in the saddle should lean toward the more forgiving gearing option. Spinning through the steep sections preserves muscular endurance better than mashing a big gear at low cadence.

Context

Starting at 425 m elevation and topping out at 660 m, Hals Pass sits at a relatively modest altitude. There are no significant altitude-related concerns for performance — oxygen availability is a non-factor here. The climb's challenge is purely mechanical: managing the variation between its gentle average and its sharp maximum.
