Tartencelloise is a local race day in Margencel, Haute-Savoie, France, scheduled for May. The exact date is yet to be confirmed. Participants can choose between a 15.5 km run, a 9.7 km run featuring 120 meters of elevation gain, or a 9 km Nordic walk, catering to those seeking either a longer distance or a shorter, undulating course.
The adult races take place in the morning, starting with the 15.5 km event, followed by the 9.7 km run and the walk.
