The Tour de Frustelle is the shortest race of the UltraChampsaur: a loop out of Pont-du-Fossé through the hedged farmland of the Champsaur, with the Petite Autane in view. The climbs are short but frequent, and the only longer one comes in the second half.
Start and finish are on the Place de la Patinoire in Pont-du-Fossé, a little over 1,100 m up in the upper Champsaur on the edge of the Écrins massif. The first four kilometres stay close to the valley floor and climb only in small steps of 40 to 50 m. The organiser routes the course through the bocage, the hedge-lined farmland of the valley, and past viewpoints of which the Petite Autane is the best known.
From km 3.9 the main climb begins: around 180 m in two kilometres, with short pitches above 30 percent. After a short break a second, steeper step of about 100 m starts at km 6.6 and leads to the high point just under 1,400 m. From there the course drops quickly over the last two and a half kilometres back to Pont-du-Fossé, where all four races of the day finish.
| Start | Length | Ø | Max. | Gain | Cat. |
|---|---|---|---|---|---|
| km 0.7 | 0.5 km | 8.6 % | 19 % | +39 m | — |
| km 1.4 | 0.5 km | 9 % | 22.3 % | +43 m | — |
| km 3.9 | 2 km | 9 % | 31.5 % | +182 m | Cat. 3 |
| km 6.6 | 0.9 km | 12.5 % | 32.1 % | +106 m | Cat. 4 |
Climb categories follow the road-cycling convention and rate the terrain itself (length and gradient) regardless of sport: Cat. 4 marks the easiest rated climbs, Cat. 1 the hardest, and HC (hors catégorie, “beyond categorization”) is reserved for the most brutal ascents. Short climbs below the Cat. 4 threshold stay unrated.
The first four kilometres invite you to think flat, but they are not quite: the small steps cost you if you take them at speed. Run them evenly and save your strength for the part that counts.
The race is decided between km 3.9 and 7.5. On the pitches above 30 percent hiking is often barely slower than running and spares the legs for the second step.
If you can still run at the top, the fast descent to Pont-du-Fossé is where you gain the most time; if you overdid the first climb, that is where you lose it again.

For most runners the Tour de Frustelle takes between one and two hours. The effort is a brisk, mostly aerobic run with two short, hard phases on the hill where the heart rate climbs clearly.
Train short hill intervals of three to eight minutes on steep ground, and practise switching deliberately between a strong hike and running. One run a week on meadow and farm tracks with small rises prepares you for the first part of the loop.
The finish is a fast descent of around 250 m. Downhill running on paths and tracks, ideally at the end of a session, makes your quads ready for it.
The race is held in early July in the morning, above 1,100 m and partly in the open. Do some training runs in warm weather and plan enough fluid for the start time.
