You can run in the lower parts
Orny, Col Fenêtre, col des Chevaux, Mille and Panossières are still impracticable on foot. Otherwise you can already try the Wall Lourtier-la Chaux or other trails below 2300m. North sides often have too much snow. The Verbier X-Plore route is almost good but for now you'll have to wait to pass by the upper ridge.
