From August 16th to 20th
For the 5th year in 2017 in a row, Grenoble is hosting the Ultra Tour des 4 Massifs (UT4M). Launched in 2013, this new trail running concept, with its start and finish lines in the very centre of the city, offers a course of 160 km through the 4 massifs surrounding Grenoble: Vercors, Taillefer, Belledonne and Chartreuse.
In 2014 the UT4M has 4 separate races for adults - the UT4M 160 km solo, UT4M 160 km 4-person relay, UT4M 90 km, UT4M 40 km - and a children’s race, the UT4M Graines de Trailers.
Why come to the Ut4M 2017?
