2023 Tour de France Stage Analysis

2023 Tour de France stage power and drag analysis — Best Bike Split

For 2023 we have once again modeled all 21 stages of the Tour using our advanced performance modeling software. Discover our new Category Climb Detection feature and utilize our Time Analysis tools to scrutinize every stage just like the pros. With these tools, identify where modifications in power, drag, weight, and rolling resistance can deliver the most significant impact on riders' performance.

This year's race kicks off in Bilbao, Spain before heading into the Pyrenees for some early fireworks, then winds through the Massif Central and finishes with a brutal Alpine block featuring stages to the Puy de Dôme, Courchevel, and Saint-Gervais Mont-Blanc. The climb detection tool really earns its keep here — with hors catégorie and Category 1 climbs scattered throughout, knowing the exact gradient demands and optimal power targets for each ascent can be the difference between a strong finish and a blown-up race. Use the Time Analysis tool on any stage to see how small changes in your CdA or weight translate to real time savings over a 4+ hour mountain stage.
