Level: ★★★★★
Departure: Aínsa, Huesca
9 - 11 September 2022



A gravel getaway between canyons, valleys and high mountains

Las Treserols is a weekend of non-competitive gravel biking with a very limited capacity. It takes place on tracks, paths, tunnels, roads and beautiful landscapes in the Aragonese Pyrenees and the National Park of Ordesa and Monte Perdido on the weekend of 10 September 2022.

In this event you will have to complete the route autonomously, following a GPS track and complying with all the rules of the Highway Code.

The route

On Saturday, the main day, the route consists of 125 kilometres and 3,400 metres of positive difference in altitude, and runs through beautiful landscapes of the Ordesa National Park, high mountains up to 2,300 metres above sea level, amazing viewpoints, gravity-defying canyons, tracks, trails and beautiful and bucolic roads.

How does it work?

The event is not a race, nor a march, it is a weekend of coexistence with a personal challenge where each athlete is obliged to respect at all times the Road Safety Law and the General Traffic Regulations in force in Spain, as well as any other regulations in force along the planned route.

It is compulsory that you have checked-in at the hotel on Friday 9th September and that you attend the briefing that we will give at 19:00. During the briefing, we will inform you in detail about the whole route on Saturday. You can organise yourself as you wish, the only requirement being to complete the complete track on Saturday during the day, starting at 9:00 am and finishing at 20:00 pm on Saturday 10 September.
