From July 26 to August 3, the world's best female cyclists will compete in the Tour de France Femmes. Victory and defeat on the roads of France will be decided not only by their legs, but also by their equipment. The TOUR Tech Briefing for Stage 3.

Tour de France Femmes 2025 - Stage 3: La Gacilly - Angers | 163,5 Kilometers

The third stage is likely to be one that the sprinters have marked on their calendars. Apart from a fourth-category climb after 34 kilometers, there are no significant topographical obstacles to overcome. The approach to Angers is flat.

The sprinters' teams will therefore do everything they can to ensure that they come down to a sprint finish. The favorites are top sprinters Lorena Wiebes and Charlotte Kool, but Marianne Vos and Elisa Balsamo are also contenders for a sprint victory.

What role does the bike play in this? Does one of the favorites have a superior machine? We explore this question in our simulation of the finish.

The number of the day: five hundredths of a second

In the simulated 200-meter sprint, with 1400 W peak power and 1250 W over five seconds – these are the astonishing power data of Lorena Wiebes – our avatar on the Cervélo S5 is the fastest, one hundredth of a second ahead of the second-placed Canyon Aeroad. The bike of top favorite Wiebes, the Tarmac SL8, is five hundredths of a second slower. Marianne Vos therefore has a slight technical advantage over Lorena Wiebes with her bike.
