Filzen Saddle

Overview

Filzen Saddle is a Category 2 climb in Austria, running 6.3 km from a valley start to a saddle summit. It gains 414 m net elevation, lifting you from 897 m at the base to 1311 m at the top. On paper it is a mid-length climb with a moderate rating, the kind of effort that fits inside a longer day without dominating it.

The number that reshapes the picture is total ascent: 525 m of climbing against only 414 m of net gain. That 111 m gap is elevation you earn and then give back, meaning the road undulates rather than climbing cleanly. Every metre of descent inside the climb is a metre you re-climb, so the actual work done exceeds what the net figure implies. Treat this as a harder climb than the net gain alone suggests.

How the Gradient Unfolds

The 6.57% average is a blend, not a constant. With 111 m of internal descent, some sections drop or flatten, which drags the average down and hides the real pitches. The steepest ramp bites at 16.18%, well above average, so the hardest metres are far tougher than the headline number.

• Flatter or descending recovery sections where you can ease off and reset
• Repeated short climbs that stack rather than one continuous grind
• A peak ramp reaching 16.18%, more than double the average, demanding your lowest gear

Pacing Notes

On an undulating climb like this, chasing even speed will burn you. Holding the same pace over a 16% ramp forces you far above threshold, and you pay for it later. Instead, pace to even effort: anchor your work to a target sustainable power output and let speed fluctuate with the gradient. Push a touch harder on the ramps only if you can recover on the flatter sections that follow, and back off before you spike.

If you do not know your ceiling, run the FTP estimator first and set a percentage target you can hold across the full 6.3 km, descents included.

Gearing

The 16.18% maximum dictates your setup, not the average. For pitches this steep over a Category 2 length, run a compact or sub-compact chainset paired with a wide-range cassette. A 34×32 gives you room; a 34×34 gives you margin if you tire or ride loaded. Spinning a low gear on the steep ramps protects your legs for the re-climbs after each descent. Check your chainset and cassette before the ride so you are not caught undergeared on the 16% ramp.

Summary

• Length: 6.3 km
• Average gradient: 6.57%
• Maximum gradient: 16.18%
• Net elevation gain: 414 m
• Total ascent: 525 m
• Category: 2

Filzen Saddle rewards riders who read the profile before the road. Pace to effort, gear for the steepest ramp, and respect the 111 m of hidden re-climbing, and this Category 2 saddle rides exactly as well as your preparation allows.
