The Senior route starts in front of the Canillo Parish Hall (Edifici del Comú de Canillo) and continues along a 1.3 km stretch of tarmac with an average gradient of 7%. It then switches to a mountain path combined with a forest trail. Runners then pass by a man-made lake and reach the mid-point (4,720 metres from the start) at an altitude of 2,050 metres (feed stop 1).
Here, the route dips down for a short while to the 5.8 km mark, following a trail into the woods with a number of small rises (but little elevation gain) until it reaches the Ribaescorxada refuge 9.2 km into the run (feed stop 2).
It is uphill on paths from here on until the 11-km mark, followed by a last flat section with a small rise to an altitude of 2,430 some 11.93 kilometres into the run (finish at Forn de Canillo chairlift).
The Junior Route from the foot of the chairlift next to the Lake of the Family Park.
We will climb 600 meters up the path to the interpretation of Nature.
From this point begins a small descent to 1,500 km where we take a path in the forest with small elevations (but without too much difference) and reach the shelter of Ribaescorjada at 4km 800 - 1 point of supply.
From the Refuge begins the ascent (part with more slope) by tracks up to 6,500 km - 2 point of supply, then take the last stretch of a plane and small ascent that will take us until the arrival at 2430 meters high at 7 349 km from the exit (arrival of the Forn of Canillo chairlift)
