Trail 100 Andorra by UTMB – Ultra 105K
Ordino
Race guide
Updated 18 July 2026
The Trail 100 Andorra by UTMB Ultra 105K is a high-mountain 105 km loop out of Ordino that packs 6690 m of positive climbing into a single circuit of the Pyrenean principality. From a start at 1305 m it climbs almost immediately toward its 2892 m high point, then spends the rest of the day and night linking refuge to refuge across the roof of Andorra before dropping back to Ordino. This is a serious mountain ultra, not a rolling trail race. With more than 6600 m of vertical over the distance the climbing is relentless, the high point sits close to 2900 m, and much of the route runs between mountain refuges where the air is thin and the ground is rocky. Runners have until Sunday 16:00 to close the loop at Ordino, and a string of intermediate cut-offs shapes how the race must be run.
The course: an Ordino loop across the high refuges
The race starts and finishes in Ordino at around 1305 m and never lets the terrain settle. The first climb hauls runners from the village up to Refugi Pla de l'Estany at 2036 m by 10.9 km, then higher still to Comapedrosa at 2245 m by 17.5 km, the shoulder of Andorra's highest ground and the zone of the 2892 m high point. From there the route drops to Coll de la Botella (2053 m, 23.7 km) before the long descent to Life Base 1 at Parc Central in Andorra la Vella, the low point of the loop at just 1068 m and 38.7 km in. The second half is a chain of refuges. The course climbs back up to Refugi Fontverd (1876 m, 46.3 km) and on to the high Refugi de l'Illa at 2458 m (53.3 km) before reaching Life Base 2 at Hotel Pic Maià (2382 m) at 63.9 km. The closing 40 km stay in the mountains, dipping to Incles (1851 m, 73.4 km), crossing Pont Tibeta (1874 m, 84.6 km) and Refugi Sorteny (1969 m, 95.1 km) before the final descent back to Ordino at 105 km.
Where the race is won or lost
The decisive terrain is front-loaded and back-loaded. The opening 17.5 km gains close to a kilometre of altitude straight into the Comapedrosa massif and the 2892 m high point; go out too hard here and the legs are cooked for the 65 km still to come. The long plunge to Andorra la Vella at 38.7 km drops more than 1300 m from the high ground, punishing quads that have been climbing all morning, and it is followed immediately by the steep re-ascent to Refugi de l'Illa at 2458 m, the highest sustained section of the second half. From Life Base 2 at Pic Maià (63.9 km) the race becomes a war of attrition across Incles, Pont Tibeta and Sorteny. None of these are single monster climbs, but the repeated 400 to 600 m rises and falls between 1850 m and 2400 m, run through the night, are where places change and where tired runners slip toward the cut-offs. Saving something for the Sorteny climb at 95 km and the final drop to Ordino is what separates a finish from a time-out.
Pacing and fuelling to the cut-offs
The cut-off structure demands steady, conservative progress rather than heroics. The first hard gate is Coll de la Botella at 23.7 km (Saturday 13:15), then Life Base 1 in Andorra la Vella at 38.7 km (Saturday 16:00) where crew can meet you. From there the barriers march through the night: Refugi Fontverd 46.3 km (18:15), Refugi de l'Illa 53.3 km (21:00), Life Base 2 at Pic Maià 63.9 km (Sunday 01:00), Incles 73.4 km (05:00), Pont Tibeta 84.6 km (08:00) and Refugi Sorteny 95.1 km (13:00), with the finish shutting at Ordino at 16:00 on Sunday. Use the two Life Bases at 38.7 km and 63.9 km as your reset points: they are the crew-accessible hubs where you can change layers, restock and eat properly. Between them the aid comes at the refuges, which are spaced 6 to 15 km apart across high, exposed ground, so carry enough food and fluid to cover a long climb at altitude. Because the second half runs overnight at 1850 to 2400 m, plan calories that still go down when it is cold and you are tired, and treat the stretch from Pic Maià to Sorteny as the section where fuelling discipline keeps you ahead of the clock.
Conditions to expect
This is a genuine high-Pyrenees course with a 2892 m high point and long spells above 2000 m, so mountain weather is the defining variable. Even in a warm valley, the ridges around Comapedrosa, Refugi de l'Illa and Pic Maià can be cold, windy and wet, and conditions swing quickly with altitude. The low point in Andorra la Vella at 1068 m may feel hot early on, making the contrast with the exposed high sections all the sharper. Expect the bulk of the second half to be run in the dark, from Life Base 2 at Pic Maià onward, across rocky refuge-to-refuge terrain where footing is technical and a good headtorch matters. Full mountain kit, including warm and waterproof layers for the high, overnight sections, is the sensible default. Plan your refuge stops knowing the temperature will drop as you climb and as night falls, and do not underestimate how much the repeated high crossings between Incles, Pont Tibeta and Sorteny will slow you when you are cold and fatigued.
