The Marmotte Pyrénées
Starting in Argeles Gazost and finishing at Luz Ardiden ski station, the 2020 Marmotte Granfondo Pyrénées is a bit of a monster. The course is 160km long with 5600m elevation gain.
The route takes you from the start in Argeles Gazost over the Tourmalet, to the Col de Hourquette d’Ancizan. You get back to Sainte-Marie de Campan via the Col d’Aspin, then climb the Tourmalet, (again). The finish is at Luz Ardiden ski station.
