What the course asks of you
The Ardèche is a high plateau cut by deep valleys, so the roads climb constantly — long, irregular cols through forests and villages decorated in the event's yellow and purple — with few flat kilometres between them.
On a route with more than 4,000 m of climbing, the pace you set on the first col decides how you ride the last one. Climb steadily, eat at the village feed stations, and treat the day as a long mountain ride rather than a race.
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 L'Ardéchoise far better than short intervals.
- Build the long day: rides of five to seven hours in the final two months, towards the 232 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 L'Ardéchoise 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.
