What the course asks of you
The long route climbs, in order, the Passo Campolongo (1,875 m), the Passo Pordoi (2,239 m), the Passo Sella (2,244 m), the Passo Gardena (2,121 m) — the Sellaronda — then the Campolongo again before the Passo Giau (2,236 m), the Passo Valparola from Pocol (2,200 m), and finally the Mür dl Giat, a short, very steep wall before the finish in Corvara.
The first passes are ridden in a huge crowd; the Giau, long and steep and well into the day, is where the Maratona is won or lost. Pace the Sellaronda as if it were only the beginning, because it is.
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 Maratona dles Dolomites far better than short intervals.
- Build the long day: rides of five to seven hours in the final two months, towards the 138 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 Maratona dles Dolomites 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.
