Riffltor

Riffltor cycling climb profile

Riffltor is an HC climb in Austria, and the headline numbers explain why it earns that label. The climb runs 19.8 km from 798 m to 2100 m, with 1302 m of net elevation gain at an average gradient of 6.59%. That is not a short, violent climb where survival over a few steep ramps is enough. It is a long aerobic load where the average gradient is already demanding before the road ever reaches its steepest pitch of 13.58%.

What it is like to ride

The defining feature is duration. At nearly 20 km, Riffltor forces you to settle into a rhythm early and defend it for a long time. A 6.59% average over that distance means the climb keeps asking for steady torque rather than offering frequent relief. The maximum gradient of 13.58% matters because it tells you the climb is not simply a uniform tempo grind. There are sharper sections in the profile, and those moments will feel much harder if you have ridden the opening kilometers above your sustainable climbing power.

The available profile does not break the climb into individual ramps, so the safest tactical reading is to treat the gradient as consistently meaningful from bottom to summit. Do not wait for one known decisive wall. Instead, assume the climb can tighten at any point and pace with enough margin to absorb those steeper pitches without crossing too far above threshold. For riders using power, anchor the effort around your known sustainable output rather than chasing speed, because speed will move around with gradient changes and elevation gain. If you need a reference point, use your /glossary/ftp as a ceiling, not a target for the entire ascent.

Pacing and gearing

Riffltor rewards restraint. The first part should feel almost too controlled, because the climb has enough length and elevation gain to expose early overconfidence. If the road is sitting near the average gradient, keep the cadence comfortable and avoid grinding simply because the pace feels manageable. That is the mistake this kind of climb invites.

Gearing should be chosen for the maximum gradient, not the average. A setup that feels efficient at 6.59% can become costly when the road reaches 13.58%, especially late in the climb when fatigue has reduced your ability to muscle over steep pitches. Use a low enough climbing gear that lets you keep cadence under control without repeatedly standing or spiking power.

The practical goal is simple: ride Riffltor as one long controlled effort with built-in protection for the steepest sections. If you arrive near the summit still able to lift the effort, you paced it correctly. If the 13.58% sections force repeated surges early, the climb will likely decide the ride well before 2100 m.
