La Ronde des Fedas (occitan for sheep) is a 13k run out and around the Causse du Larzac from L’Hospitalet du Larzac, Aveyron, France. The race takes place entirely on the plateau but this does not mean that it is flat. There is an 80m vertical climb over about 3km of the latter half of the race. You can see my tracks on Strava here.  If you are in the area, don’t miss the Museum of geology and natural history and especially the intriguing rock formations of the Failles de Canalettes, deep cracks reminiscent of the film 127 Hours!
