Stage 3

Monday July 07 2025 - Valenciennes to Dunkirk - 172 km Sprint
 

The peloton will then set off from Valenciennes, which makes its return to the route of the Tour after a 34-year absence. Dunkirk, which hosted the Grand Départ in 2001 as well as a stage start on the Tour in 2022 will be welcoming the finish of the third stage.

With just 648 metres of elevation, stage 3 is the flattest of the first three. The only obstacle is hardly worth mentioning: 2.3 kilometres at 4.5%, and it’s located far from the finish line.
