The 2017 Tour de France will take in all five of the country’s mountain ranges for the first time in 25 years.
Climbs in the Vosges, Jura, Pyrenees, Massif Central and Alps will form part of the three-week, 2,183-mile trek that starts in the German city of Dusseldorf on 1 July and finishes in Paris.
Two individual time trials bookend the race which will see defending champion Chris Froome try to win a fourth title.
“We want to favour long-range attacks,” said Tour director Christian Prudhomme.
The route, which takes in Belgium and Luxembourg, is concentrated in the south and east of France.
The Col d’Izoard, which has featured in the race more than 30 times, will be a summit finish for the first time – one of just four in the race, with two coming in the first week. This year, the first mountain-top finish was not until the second week.
Stage five finishes atop La Planche des Belles Filles, where Froome won his first Tour stage in 2012 on his way to finishing second overall as his then Team Sky team-mate Bradley Wiggins became the first British winner of the race.
Despite the mountainous nature of the route, the 2017 edition will actually have fewer climbs rated category two or harder than in recent years.
There will be 23 such climbs next year, compared to 28 in 2016 and 25 in 2015 and 2014. However, the climbs will be spread over a longer period of time, placing the onus on the riders to maintain their climbing form.
The Grand Depart in Dusseldorf opens with an individual time trial, with the second coming in the penultimate stage in Marseille.
Organisers also announced that around 10km of mountain terrain will be off-limits to roadside fans.
The move follows a crash on last year’s 12th stage on Mont Ventoux where Froome – who memorably ran part way up the mountain – Richie Porte and Bauke Mollema collided with a motorbike after crowds encroached on to the road.
