The Tour des Crêts is the classic of the Pilatrail: a loop from Véranne over every landmark summit of the Pilat massif, almost entirely on singletrack and across boulder fields. Getting round it well takes strength for long, steep climbs and sure footing on technical descents.
The course climbs straight out of the village square in Véranne. The first three kilometres rise steadily, then from km 4 comes the steepest pitch of the first half: around 320 m of gain in under two kilometres up to the Trois Dents, the rock teeth standing above the Rhône valley. A descent to the aid station on the D63 follows, then another long climb to the Crêt de l'Oeillon and its transmitter mast, reached after about 15 km.
Along the ridge you reach the Jasserie, an old mountain farm at around 1,300 m, and drop steeply from there to the Saut du Gier, the waterfall of the young Gier river. This is where the race is decided: from km 23, about 590 m of gain in just over three kilometres up to the Crêt de la Perdrix, at 1,432 m the high point of the Pilat. The final third runs back to Véranne via Le Gratteau, the Saint-Sabin chapel and the Nordet, mostly downhill.
The Pilat is a regional nature park between Saint-Étienne and the Rhône valley. The organiser puts the share of paths, singletrack and forest tracks at 98 percent. The signature terrain is the chirats, fields of loose boulders you cross on foot, and on a clear day the view runs across the Rhône valley to the Alps. At the end of May the ridges can still be cool and windy.

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 half invites overspending: the climb to the Trois Dents comes early, the field is still tight, and it is easy to run your neighbours' pace there. Hike the steep pitches from km 4 deliberately, because by the Crêt de l'Oeillon you already have more than 1,000 m of climbing done and half the ascent is still ahead.
The race is decided on the climb from the Saut du Gier to the Crêt de la Perdrix from km 23. It is the longest and steepest of the course and comes right after you have given away more than 400 m. If you reach the Jasserie ridge with something left, you can take it at an even power-hike, with poles or hands on thighs, rather than stopping on every steep step.
The trap comes afterwards: the last 15 km lose almost 900 m on technical ground. Empty your quads on the Perdrix and you lose more time descending over rocks and roots than you did on the climb.

For most age-group runners the Tour des Crêts means six to nine hours of effort. The load is uneven: long hiking stretches on steep slopes alternate with fast, technical descents, and hardly a kilometre is flat. At its core it is an aerobic endurance day punctuated by hard spikes on the steepest pitches.
The defining sections are the early climb to the Trois Dents and above all the long ascent to the Crêt de la Perdrix after more than 20 km. Train steep uphill hiking at over 15 percent for 20 to 40 minutes at a time, ideally in the second half of long sessions so it still works on tired legs.
Eccentric strength for the descents matters just as much. Downhill running on rocky ground, stairs and strength work such as lunges prepare your quads for almost 2,300 m of descent. The chirats demand concentration and ankle stability on loose blocks; drills on unstable ground help.
Build in long runs of four to five hours with plenty of vertical and use them to rehearse fuelling and kit. At 1,400 m the end of May can turn cold, which is why a waterproof jacket is on the mandatory kit list anyway.

Pilatrail is 42 km long. That distance shapes how much aerobic endurance, pace durability, and race-specific work belong in the training plan.
Pilatrail has around 2,284 m of elevation gain over 42 km. That affects pacing, muscular load, and preparation for late-race sections.
Pilatrail is classified as Mountainous, averaging 55.3 vertical metres per kilometre. 5% of the route is flat, 19% climbs moderately (2 to 6%) and 28% is steeper than 6%.
The hardest climb of Pilatrail starts at kilometre 23.4, runs for 3.1 km at an average of 19.4% and gains 593 metres. Cycling-convention rating: Cat. 2. 8 climbs are mapped in total.
Yes, Pilatrail is laid out as a loop: start and finish are in the same place.

Preparation for Pilatrail should account for 42 km, 2,284 m of elevation gain, current training load, and available training time. An adaptive plan helps place key sessions without ignoring recovery and real life.
The pacing strategy for Pilatrail should reflect 42 km, 2,284 m of elevation gain, and your current fitness. Start controlled and keep margin for sections where the profile or fatigue makes target pace harder.
