The 48 km is the long Sunday course of the Trail du Coureur des Bois de Duchesnay. Its 1,100 m of climbing comes not as one big mountain but as a chain of mid-length ascents, and the most technical ground, rocky terrain between km 38 and 40, waits until your legs have spent hours in the forest.
The first real climb starts around km 7.5, three kilometres before the Champ de tir aid station. From there the course settles into a rhythm of rise and recovery. After the Bicoque water stop at km 18.5 you reach Halte 1, and two ramps follow close behind it. Every climb in this first half is shorter than the one still to come.
The core of the race starts at the Mairie aid station at km 28. That is where the longest climb of the day begins, about 2.3 km long. It averages a little over seven percent and tops out above 17. Further rises around km 30.5 and 34.8 keep the pressure on before the rocky, technical section from the Chapelle station to km 40. After one last climb from km 41.3 comes Halte 2, and from there a little over four kilometres remain.
The race runs around Station touristique Duchesnay near Sainte-Catherine-de-la-Jacques-Cartier, on cross-country ski trails, forest roads, single track and snowshoe trails through mixed forest. Wide paths where you can roll alternate with narrow ones where every step has to be placed. Along the way the forest opens onto views of Lac Saint-Joseph and Lac Sergent.

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.
Six aid stations split the course into stages, and the two longest gaps tell you where to plan ahead. It is a little over ten kilometres from the start to Champ de tir, and another ten from Mairie to Chapelle. That second stretch holds the longest climb and two more rises, so leave Mairie with full bottles and something eaten.
The race is decided between km 28 and 40. Hike the steepest parts of the long climb rather than forcing a run, and keep your focus for the rock beyond Chapelle. On technical ground, tired feet and hesitant steps cost more time than any walking break on the hill.
The trap is the first half. The climbs up to Halte 1 are shorter and invite a pace that feels easy but is only paid for after km 28. Arrive there fresh and you gain more in the final third than you could have banked earlier.

For a recreational runner, 48 trail kilometres with 1,100 m of climbing take roughly six to nine hours. The effort is long and mostly aerobic, broken up by many climbs that you run or power-hike depending on the gradient. The hard spikes are short, but they cluster in the second half.
Everything from km 28 onward decides the race: the longest climb, more rises and then rocky ground. Build long runs whose hardest part comes at the end, for example a block of hills after two to three hours of easy running. Practise strong uphill hiking with an upright torso, since on the steepest metres it is both faster and cheaper than running.
The mix of ski trails, forest roads, single track and snowshoe trails asks for sure footing on changing surfaces. Run technical, rocky paths regularly, including tired at the end of longer sessions, so the rock between km 38 and 40 is nothing new for your feet. Strength work for ankles, calves and hips makes you steadier there.
With a late May date this is an early-season objective, and most of your build falls in winter and spring. Move the long sessions onto trails as soon as you can where you live, and use them to test the kit and fuelling that will carry you from station to station.
