The race heads west into the Alps from the foothills of the Jura mountains with the first proper mountain stage.
The first 100 kilometres from Oyonnax are fairly flat and not too demanding. Two smaller climbs, the 3rd cat Côte de Copponex (6.5 km at 4.4%) and the 4th cat Côte de Menthonnex-en-Bornes (2.7 km at 4.9%) will warm up the legs for the oncoming onslaught.
The peloton will tackle the 1st category Côte de Mont-Saxonnex shortly after Bonneville. 5.7 km at an average of 8.3%.
Almost immediately after the descent the the race head into the high alpine climbs.
The 1st category Col de Romme amounts to 8.8 kilometres at 8.9%, while the well-known climb of the 1st cartegory Colombière is 7.5 kilometres long and averages 8.5%. The climb gets steeper near the summit, where the first three riders gain time bonuses of 8, 5 and 2 seconds.
The Col de Romme and Col de la Colombière combination was last used in 2018 on a similar route finishing in Le-Grand-Bornand. Julian Alaphilippe launched an attack that day to win the stage. 1m 34s minutes ahead of chaser Ion Izagirre.
The first three riders at the finish line gain time bonuses of 10, 6 and 4 seconds.
The 8th stage of the Tour de France starts at 13.10 CEST and the race is expected to finish around 17.20 CEST.
