Trail de Montaigu.

The Découverte is the shortest distance at the Trail de Montaigu, but it is no gentle beginners' lap: the forests around Souligny and Bouilly hide a wall just past halfway that asks for about 60 metres of climbing in 400 metres. Prepare for it with strength on steep ground and legs that stay loose for the long way down to the finish.

Trail de Montaigu 2027: Course, Elevation & Route Profile

The lap starts gently. The first kilometre barely rises, then the longest climb begins at km 1.5: just under a kilometre and a half gains a little over 90 metres, steadily and without nasty surprises, and delivers you to the high ground at km 3. Until km 5 the course only undulates up there, reaching its highest point about 130 metres above the start.

Then it tips over. A fast stretch gives away almost 70 metres by km 5.5. Straight after it comes the key passage: 400 metres averaging 15 percent, which take you nearly back to where you were. From the crest at km 6 the course falls almost without interruption to the finish, three kilometres on which your legs are allowed to run.

The ground here is the forest around Souligny and Bouilly, the Oppidum and the site of Montaigu, with sections of single track. TOS Athlétisme organises the race, and the same nine kilometres also carry the team trail and the randonnée. That makes the Découverte the most compact way to get to know this terrain.

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.

Pacing Strategy

How to pace Trail de Montaigu.

Start

Start under control

More than a third of the course climbs, close to 30 percent descends, and very little is truly flat. Nine kilometres still tempt you into a road 10K mindset. So run the long climb from km 1.5 at an effort that leaves you breathing calmly at the top: it is shallow enough to run throughout, which is exactly why it is easy to overdo.

Mid-race

Hold your rhythm

The trap is the descent from km 5. Let it run fully and you arrive at the bottom with burning quads and a high heart rate, right in front of the steepest passage of the race. Ease off slightly up top, take the ramp with short quick steps or a strong walk, and leave the watch alone.

Finish

Spend what is left

This is where the race is decided, though not quite the way the ramp suggests: you gain little on it, and a lot after it. With some air left at the crest, the three kilometres to the finish are where you move past runners still looking for their rhythm.

Training plan for Trail de Montaigu: 12-week build

Base

Build the base

Age-group runners take around 50 minutes to an hour and a half for the Découverte. Across that span the effort is hard and restless: no steady pace, but a mix of brisk climbing, quick descending and one short spike into anaerobic territory when the ramp arrives.

Core

Train race pace

The centrepiece of your preparation is exactly that sequence. Find a hill of 50 to 60 metres, run down it at pace and go straight back up. Six to eight rounds with easy recovery reproduce the moment before and on the ramp better than any interval on the flat. What matters is that the hill comes straight out of the descent, because that switch from braking to driving is what hurts on race day.

Specific

Rehearse the course

Two additions round this out. Steady climbs of eight to twelve minutes build the just-below-the-limit running the long first climb demands. Relaxed, quick downhill running on forest tracks prepares the final three kilometres, where tired legs tend to land heavily and give time away.

Race week

Arrive fresh

A date at the end of April puts the build in February and March. If your winter was mostly tarmac, move into the forest once or twice a week by then at the latest, so your ankles and footing do not meet single track for the first time on race day.
