Tour de France 2026: The Watts/kg Report

How we estimate it: power = gravity + rolling resistance + aerodynamic drag (drivetrain corrected), from each climb's length, gradient, altitude and the winner's time. Rider weight comes from procyclingstats, bike at the UCI minimum 6.8 kg. W/kg is on body weight. We are using physics to derive the power to weight ratios since the power data is not shared publicly, and we are happy to update our findings should the teams and riders wish to share their power data.
