This year, Best Bike Split takes our performance modeling further than ever with AI-assisted stage analysis for the 2026 Tour de France. All 21 stages have been modeled from the route profile, terrain, stage type, equipment assumptions, and the demands of each key section. As each stage approaches, we will continue updating predictions with the latest weather so wind, temperature, rain risk, and changing road conditions can be reflected in the model.
Both free and premium members can experience each day's unique challenge firsthand with custom stage-by-stage workouts ready to upload into Zwift or a favorite training app. The workouts are built to give riders the feel of the pro race - the climbs, surges, exposed sections, time-trial demands, and fatigue patterns - while scaling targets to each athlete's own FTP.
Key Stage Highlights
Stage 1 / Barcelone Team Time Trial (19.6 km / Jul 4)
The Tour opens with a 19.6 km team time trial in Barcelona, bringing immediate GC consequences before the road stages even begin. The route is short, technical, and centered around Montjuïc, so clean team rotations, corner exits, and pacing over the Côte du Stade Olympique de Montjuïc matter more than simply holding the highest power. Coastal breezes around Barcelona could add a crosswind wrinkle, but the bigger performance risk is losing rhythm through the technical city sections and the climb.
Stage 2 / Tarragone to Barcelone (168.5 km / Jul 5)
Stage 2 runs 168.5 km back toward Barcelona and again uses Montjuïc as the decisive feature. The Côte de Begues softens the peloton before the repeated Côte du Château de Montjuïc circuits create a classics-style finale for puncheurs, GC riders, and durable sprinters. If the coastal approach is windy, positioning before Barcelona could become just as important as the final accelerations, especially with teams still nervous after the opening TTT.
Stage 3 / Granollers to Les Angles (195.9 km / Jul 6)
The first true mountain signal comes unusually early, with 195.9 km from Granollers to Les Angles and roughly 3850 m of climbing. Col de Toses, Col du Calvaire, and the high finish at Les Angles make this a long climbing day rather than a single summit test. The GC riders may not need to win the Tour here, but anyone who is under-fueled, badly positioned, or exposed to wind on the high Pyrenean roads could lose time fast.
Stage 6 / Pau to Gavarnie-Gèdre (186.2 km / Jul 9)
Stage 6 is the first major Pyrenean showdown: 186.2 km from Pau to Gavarnie-Gèdre with 4100 m of climbing and the historic Col d'Aspin and Col du Tourmalet before the summit finish. Pau and the Tourmalet are deeply tied to Tour history, and the Tourmalet's exposed upper slopes can make wind, temperature, and pacing decisive. The final climb to Gavarnie-Gèdre gives this stage a second punch after the famous climb, so riders who spend too much energy over the Tourmalet may pay for it late.
Stage 9 / Malemort to Ussel (185.5 km / Jul 12)
Stage 9 looks like a breakaway and classics-rider trap: 185.5 km from Malemort to Ussel with 3300 m of climbing across rugged Corrèze terrain. Suc au May, Côte de la Croix du Pey, and Mont Bessou are not giant Alpine passes, but the repeated climbs create constant changes in rhythm. If ridge winds are active, this could become a hard day to control, with cross-headwind sections making the chase harder than the profile first suggests.
Stage 10 / Aurillac to Le Lioran (166.6 km / Jul 14)
The Bastille Day stage from Aurillac to Le Lioran packs 3800 m of climbing into 166.6 km through the Massif Central. Côte de Pailherols, Col de la Griffoul, Col de Prat de Bouc, Côte de Murat, and Puy Mary - Pas de Peyrol create a jagged profile where repeated efforts matter more than one sustained climb. The exposed plateaus can make wind direction a real tactical factor for breakaways, especially if a cross-tailwind encourages long-range attacks.
Stage 14 / Mulhouse to Le Markstein Fellering (155.3 km / Jul 18)
Stage 14 is a compact but serious Vosges mountain stage, covering 155.3 km with 3800 m of climbing. Grand Ballon, Col du Page, Ballon d'Alsace, and Col du Haag keep the race on repeated climbs and ridge roads where recovery is limited. The Vosges are often underestimated, but wind on the high ridges and fast weather changes can amplify attacks and make descending or regrouping difficult.
Stage 15 / Champagnole to Plateau de Solaison (183.9 km / Jul 19)
Stage 15 brings the race toward Haute-Savoie with 183.9 km and 3950 m of climbing before the summit finish at Plateau de Solaison. Côte des Rousses, Le Salève - Col de la Croisette, Côte du Mont, and the final ascent stack fatigue before the second rest day. This is a stage where nutrition, heat management, and conservative pacing can matter as much as peak climbing power, because the final climb arrives after a heavy accumulated load.
Stage 16 / Évian-les-Bains to Thonon-les-Bains Individual Time Trial (26.1 km / Jul 21)
The only individual time trial is a 26.1 km test from Évian-les-Bains to Thonon-les-Bains with 500 m of climbing and the Côte de Larringes as the key obstacle. This is not a pure flat aero test: riders need to balance equipment choice, climbing efficiency, and speed along Lake Geneva. Lake-effect wind could be important, with crosswinds changing how aggressively riders can stay in the aero position on exposed sections.
Stage 19 / Gap to Alpe d'Huez (127.9 km / Jul 24)
Stage 19 is short by Tour mountain standards at 127.9 km, but it finishes on Alpe d'Huez after Col Bayard, Col du Noyer, and Col d'Ornon. The 21 bends of Alpe d'Huez make this one of cycling's most recognizable arenas, and the shorter stage distance should make the racing sharper rather than easier. Gap-area valley winds can complicate the approach, but the final selection should come from repeated climbing pressure and the last ascent.
Stage 20 / Le Bourg d'Oisans to Alpe d'Huez (170.9 km / Jul 25)
Stage 20 is the queen-stage style test of the 2026 route: 170.9 km from Le Bourg d'Oisans to Alpe d'Huez with 5450 m of climbing. Croix de Fer, Télégraphe, Galibier, and Sarenne arrive before a second consecutive Alpe d'Huez finish. The Galibier is the high point of this Tour, and exposed high passes could make wind direction decisive for long-range attacks. If the race is still close, this is the day most likely to reshape the final podium.
Stage 21 / Thoiry to Paris Champs-Élysées (133 km / Jul 26)
The final stage keeps the Paris finish but is no longer just a ceremonial sprint setup. The 133 km route from Thoiry to the Champs-Élysées includes the Côte du Pavé des Gardes and repeated trips over the Côte de la Butte Montmartre, adding cobbles, corners, and punchy climbing before the traditional finish. Crosswinds are less likely to decide the finale than positioning and road furniture, but the Montmartre laps make this a real tactical stage.
Time Trial and Team Watch
Remco Evenepoel, Filippo Ganna, Tadej Pogačar, Jonas Vingegaard, and Florian Lipowitz are the key time-trial names to watch across Stage 1 and Stage 16. The TTT should reward deep, disciplined teams such as UAE Team Emirates-XRG, Visma-Lease a Bike, Red Bull-Bora-Hansgrohe, and Netcompany Ineos. Stage 16 is more nuanced than a flat power test, giving Evenepoel and Ganna a clear target while forcing GC riders to manage climbing power, equipment choice, and possible Lake Geneva crosswinds.
GC Riders to Watch
Tadej Pogačar enters as the rider everyone is measuring against, with UAE Team Emirates-XRG built around controlling the race and exploiting repeated climbing days. Jonas Vingegaard and Visma-Lease a Bike remain the most obvious counterweight, especially across the Pyrenees and the final Alpine block. Remco Evenepoel and Florian Lipowitz give Red Bull-Bora-Hansgrohe tactical flexibility, while Paul Seixas brings home-race intrigue and high-upside climbing talent. The route's early Pyrenees and double Alpe d'Huez finish mean consistency may matter as much as one spectacular attack.
Sprint and Puncheur Riders to Watch
Jasper Philipsen, Tim Merlier, Biniam Girmay, and Arnaud De Lie headline the fast-finish group, but the 2026 route does not offer many completely simple sprint days. Mathieu van der Poel, Mads Pedersen, Julian Alaphilippe, and Ben Healy are especially interesting on stages where climbs, wind, and technical finishes blur the line between sprint stage and classics day. Stages 2, 8, 9, 10, and 21 are the type of days where durable riders can punish pure sprinters.
Weather and Wind Modeling
The first published BBS models should be treated as baseline performance projections. As each stage approaches, live weather will matter most on the Barcelona coastal roads, the open approaches toward Bordeaux and Nevers, the Massif Central and Vosges ridgelines, the Lake Geneva time trial, and the exposed high Alpine passes around Croix de Fer, Galibier, Sarenne, and Alpe d'Huez. Crosswinds may not define every stage, but when they appear they can change the energy cost of the race long before the final climb or sprint.

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.
