FATMAP difficulty grade
This route, on the sunnier side of the valley, travels through forest and high meadows to a dramatic traverse between the Aiguillette des Houches and Brévent, opposite Mont Blanc.
But make sure you look the other way too — the views are panoramic, stretching to the jagged Fiz and Aravis mountain ranges.
At the finish of the run, you can take the Brévent cable-car down to Chamonix.
You could also run trails down to town if you like. Check out Run the Alps trip options here: https://runthealps.com
