What the course asks of you
The long route crosses the Allgäu and Vorarlberg Alps: the Riedbergpass, one of Germany's steepest paved passes, and the Hochtannberg, before the return over the Gaichtpass (4.4 km at 5 %) about 16 km from the finish. The shorter routes stay in the Tannheim valley and over the Oberjoch.
On the 214 km, the Riedberg comes early and is steep: climb it gently. The Gaichtpass at the end is short, but it comes after a long day.
How to prepare
The general shape of a good preparation, which Event Coach turns into a plan for your fitness, time and date:
- Train long climbs: steady efforts of 30 to 60 minutes just below your threshold match the cols of the Rad-Marathon Tannheimer Tal far better than short intervals.
- Build the long day: rides of five to seven hours in the final two months, towards the 214 km of the route you choose.
- Practise eating and drinking on a schedule, and descending: a mountain day is as much going down as going up.
Pacing mistakes to avoid
The mistakes that cost riders the most on a day like this:
- Treating the first climb of the Rad-Marathon Tannheimer Tal as a race: a long col ridden above the pace you can hold for hours costs you the rest of the day.
- Saving nothing for the last climb, where the most kilometres are already in your legs.
- Skipping food on the descents: the next climb starts with what you ate on the way down.
