We've modeled all 21 Tour stages using our state-of-the-art performance modeling software. Leverage our Time Analysis tool to analyze each stage with the precision of a seasoned professional. This tool will empower you to pinpoint optimal adjustments in power, drag, weight, and rolling resistance that can profoundly influence rider performance.
Some Keys Stage Highlights
Stage 1 / Florence to Rimini (203.6 km / June 29)
The Tour kicks off with a hilly stage in Italy, which is perfect for a breakaway. The peloton may or may not allow the escapees to shine, but with a punchy finish, a big name could steal the spotlight. For all the data and details see the Stage 1 model.
Stage 7 / Nuits-Saint-Georges to Gevrey-Chambertin (25.3 km ITT / July 5)
The first individual time trial will shake up the GC standings. The stage, while not overly mountainous, but does have a challenging bump that could hinder heavier TT specialists. Expect the top GC riders to excel here, demonstrating their time-trialing prowess. For all the data and details see the Stage 7 model.
Stage 14 / Pau to Saint-Lary-Soulan Pla d'Adet (151.9 km / July 13)
This stage features the legendary Col du Tourmalet and finishes with the hors catégorie Saint-Lary-Soulan / Pla d'Adet. The GC hopefuls will need to prove their climbing strength, setting the stage for an intense battle just before a rest day. For all the data and details see the Stage 14 model.
Stage 19 / Embrun to Isola 2000 (144.6 km / July 19)
High-altitude climbs dominate this stage. The final ascent to Isola 2000, with its 7.1% gradient, will create significant gaps among the contenders. This stage is crucial for those aiming for the yellow jersey. For all the data and details see the Stage 19 model.
Stage 21 / Monaco to Nice (33.7 km ITT / July 21)
The Tour concludes with a time trial on the Mediterranean coast. With two tough climbs early on, pacing will be key. This stage offers a thrilling end, especially if the GC battle is still close. It also previews the Olympic TT, with key absences like Filippo Ganna focusing on Olympic gold. For all the data and details see the Stage 21 model.
How Best Bike Split Models the Tour de France
Best Bike Split's Tour de France stage analysis is built on the same physics-based power modeling used by athletes and coaches to plan real-world races. Each stage is modeled using route elevation data, distance, aerodynamic and rolling resistance assumptions, the same inputs that drive a Best Bike Split race plan. As race day approaches, models are rerun to pull in live weather data layers in wind speed, wind direction, temperature, and precipitation risk so the model reflects the most accurate weather predictions. The result is stage analysis grounded in watts, not just narrative, giving cyclists a more meaningful way to understand what each day of the Tour actually demands. Whether you're following the GC battle, chasing a breakaway stage, or just trying to understand why a 127 km stage to Alpe d'Huez can be harder than it looks on paper, Best Bike Split's stage modeling gives you the numbers behind the race.
