Best Bike Split: AI Race Pacing & Power Plans

Best Bike Split is a precision race-planning platform built for athletes who want to leave nothing to chance on race day. By combining a sophisticated math and physics engine with your personal power data, bike setup, and detailed course profiles, it generates a customized pacing strategy designed to deliver your fastest possible bike split. Rather than guessing at effort levels, you get a data-backed plan that accounts for elevation, surface conditions, and aerodynamics. The platform goes beyond simple predictions by calculating key variables like CdA (aerodynamic drag), rolling resistance, and mechanical drivetrain losses, then layering in real-time weather conditions to fine-tune your race-day power targets. Whether you're mapping out a hilly triathlon bike leg or a flat time trial, Best Bike Split translates complex physics into an actionable pacing roadmap. Beyond individual race prep, the tool supports deeper performance analysis, letting athletes and coaches compare projected plans against actual race outcomes to refine future strategy. With AI-powered workout building, device integrations, and tiered subscription options, it serves everyone from first-time racers dabbling with free tools to dedicated multi-event athletes and coaches managing entire training programs.

1. Create an athlete profile with key metrics such as weight, height, FTP, and bike specifications. 2. Choose an existing race course from the platform's library or build a custom course profile. 3. Let the engine calculate CdA, rolling resistance, and mechanical loss based on your inputs. 4. Factor in expected weather conditions for race day accuracy. 5. Review your generated power plan and adjust pacing strategy as needed. 6. After racing, compare your actual performance data against the predicted plan to refine future strategies.
