Deca d'Escalquens is a trail-running event in Escalquens, Haute-Garonne, Occitanie, in southwestern France. It takes place in early February and features two options: a 5 km trail run and a 10 km trail run.
The 10 km is the more popular race, with over 400 runners at the last edition, while the 5 km had more than 100. This event serves as a local winter trail day, featuring a main 10 km race and a shorter option for those who prefer the same environment without the longer distance.
