Best Bike Split

Best Bike Split is a race planning tool for cycling and triathlon. Athletes set up a profile with data such as weight, height, FTP, MaxHR, bike type, wheel type and components, then select or create a course. The math and physics engine calculates CdA, rolling resistance and mechanical loss, combines them with course distance, altitude changes, wind and weather, and outputs a variable power pacing plan intended to produce the fastest bike split given course conditions and power limitations. The page states the tool is used by over 150,000 athletes and coaches, supports Ironman racing, offers a free Athlete Basic plan, paid premium plans, and coaching subscriptions, and integrates with Hammerhead Karoo, Wahoo ELEMNT, Garmin, TrainingPeaks, Zwift and Garmin Connect.
