One of the most famous Gran Fondo’s of them all, Le Marmotte is a bucket list ride – and this year it takes place on July 4.

This stunning French Alps sportive sets off from Bourg d’Oisans, and runs through Isere, Savoie, the Alps – and climbs over some of most respected passes in cycling – including the iconic le Galibier(2642m), le Lautaret(2057m), and the famous 21 hairpins of the Alpe d’Huez(1880m).

15 Tips to Ensure you are Always Motivated to go for a Cycle

The ride finishes atop the almighty Alpe d’Huez, which is closed to all vehicles from 2pm – 6pm, so it’ll be just you, and the bike (and around 4,000 other riders there to support you!). In total, you’ll cover  5,180 m – that’s 16,990 ft – of climbing. Eye-watering, but certainly a major achievement.

Entry is 85 euros – find out more – and if you fancy the Alpe d’Huez but not the distance, there is this shorter version at 47 miles.
