Tour de France Femmes 2025 - Stage 2: Brest - Quimper | 110,4 Kilometers
The second stage is also short and is likely to be similar to day 1 due to its similar structure. Again, there are two final laps to ride, and again there is a short climb in the way, the Côte du Chemin de Trohéir.
There is a 70-meter climb to master at 1,200 meters, 4.7 kilometers before the finish line. On the one hand, that's not much, but the climb starts with a 100-meter section at 14%, followed by 100 meters at 11%. This is where powerful classic riders can make a difference, break away, and carry their lead over the crest.
What does a 14% gradient mean for acceleration? Which bike pushes ahead here? Our simulation provides the answer.
The number of the day: one tenth of a second
Our calculation shows that one kilo of excess weight does not make as much difference when sprinting on a steep section as one might intuitively assume. However, this is also due to the initial conditions: the riders will enter the hill with momentum, which reduces the influence of excess weight.
Over the first hundred meters, the heaviest bike is only a good tenth of a second behind, according to our calculations. Unsurprisingly, the S5 is again in the lead – because it is almost as light as allowed and aerodynamic. It doesn't get any better than this.
