The Trail des Arts starts and finishes inside the Abbey of Cluny, and its shortest course comes down to a single climb: nearly three flat kilometres lead to its foot, then the route goes up and back to the abbey. As a first trail race it sets one clear task, and one you can prepare for directly.
The course is a loop in three clear parts. From the abbey it stays almost level for about three kilometres. At kilometre 2.9 the only real climb of the lap begins. Over just under two kilometres you gain 135 metres at around seven percent on average, and individual ramps get noticeably steeper. Nearly all of the day's climbing therefore comes in one piece.
At the top a short, almost level stretch runs to about kilometre 5.6. From there the route drops quickly, losing a little over 130 metres in not much more than a kilometre. From kilometre 7 it is flat again all the way to the finish. Your watch will show around 8.4 kilometres at the end, slightly more than the name promises.
The Trail des Arts is run by a team of engineering students, and its appeal lies in the setting: start and finish are in the Abbey of Cluny, surrounded by a landscape of forest paths, vineyards, wooded hills and ridges. Gourmet refreshments are part of the shortest course too, so you do not have to run the long distance to try them.
| Start | Length | Ø | Max. | Gain | Cat. |
|---|---|---|---|---|---|
| km 2.9 | 2 km | 6.8 % | 13.6 % | +135 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 flat opening is also this course's biggest trap. Without a gradient a high pace feels cheap, and if you run the first three kilometres like a road race you reach the foot of the climb with your heart rate already up. Run this part at a pace where you could still speak in full sentences.
The race is decided between kilometres 3 and 5. Nearly all the climbing sits here, and with it the biggest time gap between a good day and a bad one. Start the climb deliberately below what feels possible, shorten your stride and walk the steepest ramps briskly when running them costs more than it returns. Do not stop at the top: the level stretch is your recovery, and it happens on the move.
Stay loose on the descent and brake only where the ground demands it. After that it comes down to what you have left: the flat final section rewards anyone who did not overreach on the hill, because level ground is where time can still be won back.

Age-group athletes are out for roughly 50 to 75 minutes here. The effort is mostly aerobic with one hard block in the middle: depending on your form the climb takes 15 to 25 minutes and pushes you close to threshold. There is little true recovery afterwards, because the descent needs your full attention.
The race turns on that one climb, so it deserves the key session of your week. Hill intervals of eight to twelve minutes on a gradient of around seven percent match the demand. Build over the weeks towards one continuous block as long as the climb itself. Practise switching between running and brisk walking as you go, because on the steepest ramps walking is the right call even at this distance.
With flat kilometres before and after the climb, speed on level ground belongs in the preparation as well. A good key session: warm up, run one long hill block, jog easily down and add one quick flat kilometre at the end. It teaches you to get your legs turning again after the descent.
The race is on 10 April, so most of your preparation falls in winter and early spring. Move at least one run a week from tarmac onto forest paths during that time, so your ankles and footing adapt to uneven ground and race day is not the first time you run a descent on this kind of surface.
