Continuing north towards the Alpine crescendo, stage 17 covers 174.7km from Chambéry to Voiron. Billed by the organisers as a sprinters' stage, it may deliver a battle between breakaway artists and sprinters’ teams.
The first 60 kilometres wind through the Bauges regional natural park on roads tailor-made for a breakaway, with four categorised climbs including the Col des Prés at 1,142 metres before the route loops back to Chambéry. Rolling terrain then carries the race through the Chartreuse regional natural park for the next 77 kilometres to the intermediate sprint in Colombe, after which the final 30 flat kilometres offer the peloton a chance to regroup before Voiron.
