Using our math and physics engine we've created race plans for this year's events based on a typical cyclist for the event, their TT bike and the course conditions. Each race plan includes a detailed power plan with downloadable files for use in training and on race day as well as a course map, forecasted weather conditions, yaw angles, course gradient breakdown and our Time Analysis Tool. With the Time Analysis Tool you can adjust power, drag, weight and rolling resistance then see how it effects your race in real time.
The 2018 championships span four locations and multiple categories, making this one of the more comprehensive modeling efforts we've done for a domestic racing event. The pro ITT in Knoxville is the marquee event, but the Vail Pass-adjacent collegiate and masters courses in Grand Junction offer their own unique challenges — riders who underestimate the altitude penalty on power output often pay for it in the final kilometers. Use the Time Analysis tool to dial in your specific power and CdA numbers and see exactly where you can gain or lose time against the benchmark splits we've modeled for each category.
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.
