Join Lucas, UIMLA mountain leader, in this 3-day trail running traverse across the Jura in France, from Bellegarde to Morez.


3 Days

May - Nov


Are you in love with the great outdoors? Do you want to fully enjoy running, without pressure or a stopwatch? Do you want to feel free in an unspoilt natural environment? Then this trail running traverse in the Jura is perfect for you!

During this trip we will cross the French section of the Haut Jura chain, from Bellegarde s/ Valserine to Morez. In order to make this trip light and autonomous, I planned sleeping in guarded accommodations and avoiding car transfers. Indeed, at the end of the trip we return by train, and voilà!

In total, we will cover more than 90km, with a total altitude change of +4100m / -3700m.

Does this trail running traverse sound interesting? Then please contact me and let’s go on this adventure! I would love being your guide in this region I know so well.
