Try Us For Free See A Demo Plan Best Bike Split FAQ What is Best Bike Split? Best Bike Split is a physics-based cycling and triathlon race planning tool used by over 150,000 athletes and coaches worldwide. It uses your power data, real course files, weather forecasts, and aerodynamic modeling to calculate your optimal variable power pacing plan — so you can predict your bike split and execute the perfect race day strategy. How does Best Bike Split create a pacing plan? Best Bike Split's math and physics engine models the forces acting on a rider — aerodynamic drag, rolling resistance, gravity, and wind — for every segment of your course. It combines your FTP, bike profile (CdA and weight), real course elevation data, and forecasted weather conditions to calculate the most efficient variable power output for your target finish time. The result is a personalized pacing plan, not a generic percentage of FTP. Does Best Bike Split work for Ironman racing? Yes — Ironman racing is one of Best Bike Split's core use cases. Our database includes the vast majority of Ironman-branded courses worldwide, from Kona and Frankfurt to local regional events. The platform models the full 112-mile bike leg accounting for course profile, wind, heat, and your personal power data to help you arrive at T2 with the legs to run your best marathon. Do I need a power meter to use Best Bike Split? A power meter is strongly recommended for race day execution, but it is not required to create a plan. Best Bike Split can build plans using estimated power data, and our Wahoo ELEMNT / Garmin integration allows you to follow your power and speed targets in real time on your head unit. For athletes racing without a power meter, speed-based targets are also available. Is Best Bike Split free to use? Yes — Best Bike Split offers a free plan that includes one race plan, one bike profile, basic analytics, and file downloads. No credit card is required to get started. Premium plans unlock unlimited race plans, the AI Workout Builder, AI Assistant, advanced weather modeling, and full analytics tools starting at $10/month billed annually. Can coaches use Best Bike Split for their athletes? Yes. Best Bike Split offers dedicated coaching subscriptions that allow coaches to create and manage athlete profiles, build race plans on their athletes' behalf, and share pacing strategies — all from one account. The Coach Annual plan supports unlimited athletes, while the Athlete Plus plan is designed for athletes who also coach a small number of paid athletes. How accurate are Best Bike Split's race predictions? When power data, course information, and weather inputs are accurate, Best Bike Split's physics-based model typically predicts bike split times within 2–3%. Our predictions are validated every season by thousands of athletes at Ironman events, triathlons, and gran fondos worldwide — and by our work with WorldTour professional cycling teams including EF Pro Cycling, Lidl-Trek, and Canyon//SRAM Racing. Does Best Bike Split integrate with Garmin and Wahoo? Yes. Best Bike Split integrates with Wahoo ELEMNT devices to display your power and speed targets in real time along the course on race day.
