Font Romeu Nature Trail.
The Marathon du Carlit is the long course of the Font Romeu Nature Trail, and almost all of it runs above 1,750 metres. Its high point sits close to 2,600 m, and most of the climbing is packed into three long, steep ascents. Getting to the finish means preparing for a long day in thin air and for a great deal of steep descending.
Font Romeu Nature Trail 2027: Course, Elevation & Route Profile
The loop starts and finishes in Font-Romeu, and the start is also the lowest point of the day. The first four kilometres rise in short waves before the first real ascent begins at km 4.4: almost two and a half kilometres and around 300 m of gain, topping out on stretches of trail where walking is the only sensible gait. After a descent, a second steep ramp from km 8.5 lifts you above 2,100 m.
The heart of the race lies between km 13.8 and 16.5, where the course climbs a little over 350 m in one push to its high point, then drops for some six kilometres to roughly 2,000 m. From km 25.7 a longer, steadier climb leads onto a high plateau around 2,180 m, and a descent plus one last ramp from km 36 hand over to the long run-out down to the finish.
The race is held in June in the Catalan Pyrenees, and altitude shapes this course more than any single ramp: a large part of the day is spent above 2,000 m. Aid points sit at km 8, 22.5 and 32.5. Between the first and second of them you meet the second ramp and the summit climb, the hardest fourteen kilometres of the loop.

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.
How to pace Font Romeu Nature Trail 2027.
Start under control
The three aid points split the race into four sections, and the second is the expensive one. Take the first eight kilometres, including the first big ascent, easily enough that you could still chat at the km 8 station. Power-walk the steepest pitches near the top rather than forcing them at a run.
Hold your rhythm
The day is decided on the summit climb from km 13.8. It arrives after two hard ramps and takes you to almost 2,600 m, where every overreach costs far more than it would down in the valley. Settle into a steady, strong hiking rhythm there and eat beforehand, because six kilometres of descending still separate the top from the next station.
Spend what is left
That long descent from the high point is the trap. Let it run and your quads pay on the climb from km 25.7 and over the final six kilometres, which are almost entirely downhill. On this loop, short controlled steps on the way down end up faster than bold ones.
Training plan for Font Romeu Nature Trail 2027: 12-week build
Build the base
For a recreational runner the Marathon du Carlit means roughly six to nine hours on the move. The effort is mostly easy aerobic work, broken by long, strength-heavy steep sections where you hike rather than run. It is closer to a long mountain day than a running race, and the preparation should look like one.
Train race pace
The summit climb to the high point and the descents that follow decide the race. Build long mountain sessions with the hardest climb placed in the second half, and practise brisk uphill hiking on genuinely steep slopes. One such outing of several hours a week, in the months before the race, is worth more than extra flat mileage.
Rehearse the course
With the whole course between about 1,750 and 2,600 m, altitude belongs in the plan. If you can, arrive a few days early or schedule training weekends at a similar height. Expect a higher heart rate at the same pace than at home, and pace by breathing and feel.
Arrive fresh
The second priority is eccentric strength: descents of several hundred metres at the end of long sessions, plus strength work for quads and calves. Practise carrying your own fuel between widely spaced stations too, since from km 8 to km 22.5 you rely on what you have with you.
