Kalk Trophy: Course, Elevation & Route Profile

Course & Elevation

The mass start goes off at 11am at the Bernegger works site in Gradau near Molln, on tarmac at 437 metres above sea level. The sealed surface lasts only a few hundred metres; from there the course climbs the Dorngraben forest road on gravel the whole way. The opening kilometre actually drops slightly before the first of six climbs begins at kilometre 1.75.

The climbs get longer towards the end, not gentler. From kilometre 2.78 come 1.1 kilometres at 12.1 percent, and from kilometre 4.8 the heart of the race: 2.3 kilometres averaging 11.3 percent, 257 metres of vertical in one block, with ramps up to 31.5 percent. Immediately after, at kilometre 7.28, sits the steepest point on the course at 38.6 percent. Almost 47 percent of the route counts as steep climbing, only eight percent is flat.

The final third runs into the working Pfaffenboden quarry. The gravel gets coarser, the surroundings turn industrial, and the finish sits on the extraction plateau at roughly 1,130 metres. The exact distance can shift by a few metres from one edition to the next, because it depends on how far quarrying has progressed in the finish area. Kit is carried up to the finish, and a bus shuttle brings you back down to the valley.

Pacing Strategy

An uphill race with no descent forgives nothing at the start, because there is no section where your breathing settles. The slightly downhill opening kilometre is the only place you can go clearly too hard, and in a mass start that is exactly what happens.

The race is decided from kilometre 4.8. Two and a half kilometres above eleven percent, after roughly 300 metres of climbing already in the legs, split the field for good. The start time compounds it: at 11am in early August the sun is high, the upper part of the course sits in open quarry ground with no shade, and the organiser's own report on the previous edition called it a battle with the heat. Decide how much you will drink before the start, not on the way up.

The trap is the short ramps beyond 30 percent on loose gravel. They force either an anaerobic spike or a dismount, and out of the saddle the rear wheel breaks traction easily on coarse ground. Pick your gear before the ramp and decide early whether you are going to push.

Training plan for Kalk Trophy: 12-week build

Expect roughly 45 to 90 minutes depending on your level. The demand is one continuous effort at or just above threshold, broken only by short anaerobic spikes on the steepest ramps. There are no recovery sections in the profile: 83.7 metres of vertical per kilometre spread across six climbs that all point the same way.

The race is decided between kilometre 4.8 and 8.6, where the longest gradients land on top of accumulated fatigue. On top of that comes a technical element in the upper section: on coarse gravel at low speed it is traction that limits you, not power.

Conditions belong in the plan. A mass start at 11am in August, with the closing kilometres in a shadeless quarry, means a build done entirely in cool weather meets a demand on race day it has never rehearsed. A handful of climbing sessions ridden deliberately in midday heat, plus a drinking strategy worked out in advance, are worth more here than extra watts.

The core of the preparation is long climbing intervals of 20 to 45 minutes unbroken on gradients around ten percent, ridden at the intensity you intend to hold in the race. Add low-cadence strength endurance for the sections above 20 percent, and practise steep seated climbing on loose ground. That is a skill in its own right, and it cannot be acquired on tarmac.
