Race guide
Updated 19 July 2026
The Trail 80K at Trail 100 Andorra by UTMB is a long, high-mountain ultra covering 79 km with 3618 m of vertical gain and a high point of 2712 m, looping out of and back into the village of Ordino. It links the high ground above Arcalís with a long tour across Andorra's valleys and ridgelines before returning through the capital area and climbing home. What defines the Trail 80K is its big early climb to the Coma Arcalís high country followed by a long, undulating middle and late section that never truly lets up. It is a race for runners comfortable spending many hours on their feet at altitude, who can climb hard early, keep moving through a demanding overnight middle, and still find a final effort back up to Ordino.
The course: Arcalís high ground, then the long way home
From Ordino at 1325 m the Trail 80K climbs hard to the Coma Arcalís high country, reaching Coma Arcalis 1 at 14.8 km (2238 m) and Coma Arcalis 2 at 21.2 km (2202 m), with the course topping out at its 2712 m high point up here. This front-loaded ascent is the biggest single push of the race and sets up everything that follows. From the high ground the route works its way across a long chain of checkpoints: Refugi Sorteny at 30.7 km (1956 m), Borda del Pirot Ransol at 41.1 km (1921 m), then a drop to Canillo at 48.8 km (1544 m), the crew point. The late course climbs again to Llac Engolasters at 59.6 km (1633 m), descends to Parc Central at 69.8 km (1019 m) — the lowest point and second crew point — before the final climb back to Ordino at 78 km (1311 m). With 3618 m of climb spread across this loop, the terrain rolls constantly between high ridges and valley floors.
Where the race is won or lost
The opening climb to Coma Arcalís is the defining early effort. Gaining from 1325 m to 2238 m over the first 14.8 km, and cresting at 2712 m, it is long, high, and comes when the whole race still lies ahead. Runners who attack it too aggressively will pay across the many kilometres that follow; those who climb it steadily arrive on the high ground with the reserves needed for a long day and, for many, a night on the trail. The race is truly decided in its long back half. After the descent to Canillo, the late climb to Llac Engolasters (59.6 km) and the drop to Parc Central (69.8 km) test legs that have already absorbed most of the climbing, and the final ascent from the 1019 m low point back up to Ordino at 1311 m is a genuine sting at 78 km. Holding pace and mental focus from Canillo onward — through the two crew points — is what separates a strong finish from a grind to the line.
Pacing and fueling to the cut-offs and crew points
The Trail 80K has cut-offs strung across its length, including Coma Arcalis 1 (14.8 km) by Fri 11:00, Coma Arcalis 2 (21.2 km) by Fri 13:00, Canillo (48.8 km) by Fri 21:30, Llac Engolasters (59.6 km) by Sat 00:00, Parc Central (69.8 km) by Sat 02:45, and the Ordino finish (78 km) by Sat 05:00. The two crew points at Canillo (48.8 km) and Parc Central (69.8 km) are your key resupply and reset opportunities in the demanding second half — plan drop-bag and crew logistics around them. Aid is spaced roughly every 6 to 15 km, with longer carries such as the 14.8 km opening climb to Coma Arcalis 1 and the leg from Borda del Pirot Ransol to Canillo. Because the biggest, highest climb is unsupported until Coma Arcalis 1, carry enough fluid and calories to fuel the full ascent. As the race stretches into the night, eat consistently on every climb, keep on top of hydration on the exposed high sections, and use the Canillo and Parc Central crew stops to refuel properly before the closing climb to Ordino.
Terrain and conditions to expect
This is a high Pyrenean course, reaching 2712 m in the Coma Arcalís high country and spending its early kilometres well above 2000 m before rolling through Andorra's valleys and ridgelines. Expect rocky, technical alpine trail on the upper Arcalís section, followed by a long mix of mountain paths, refuge tracks, and valley approaches as the loop makes its way toward Canillo, Engolasters, and the Parc Central area. With cut-offs running from Friday into Saturday, most runners will be out overnight, so cold, wind, and changeable weather on the high ground are real factors — carry mandatory mountain kit and a headtorch, and be ready for a wide temperature range between the exposed 2712 m high point and the lower town sections around 1000 m. The combination of a big early climb, a long undulating middle, and a final ascent back to Ordino makes the Trail 80K a true mountain endurance test where steady pacing and disciplined fueling matter as much as raw climbing strength.
