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. 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 to use Best Bike Split?

1. Create an athlete profile with weight, height, FTP, MaxHR, bike type, and components. 2. Select an existing course or build one with the Course Builder using real elevation data. 3. Generate a power plan from the physics engine for your target finish time. 4. Sync the plan to Garmin, Wahoo ELEMNT, or Hammerhead Karoo and follow it in real time on race day.

Best Bike Split Core Features

Course Builder

Build courses from real elevation data with automatic detection of bridges, tunnels, and road surface types, then generate accurate pacing plans without waiting for official course files.

AI Workout Builder

Create highly personalized, structured workouts tailored to specific race scenarios and individual training goals for cyclists and coaches.

AI Assistant

Premium feature that provides expert guidance on race plans, training, nutrition, and more, drawing on deep knowledge of endurance cycling and triathlon coaching.

Analytics Tool

Analyze ride data with a Time Analysis what-if simulation, aerodynamic drag (CdA) estimation, yaw angle and gradient analysis, and weather data.

Time Analysis Tool

Vary Power, Drag, Weight, and Rolling Resistance for any model run to see the estimated impact on overall race time and per-segment performance in real time.

Bike Computer Integration

Follow your power and speed targets in real time on Garmin, Wahoo ELEMNT, and Hammerhead Karoo head units on race day.

Best Bike Split Use Cases

Best Bike Split Frequently Asked Questions

What is Best Bike Split?

How does Best Bike Split create a pacing plan?

Its 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, and forecasted weather to calculate the most efficient variable power output for your target time.

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. You can build plans using estimated power, then follow power and speed targets through Garmin, Wahoo ELEMNT, or Hammerhead Karoo integrations.

Is Best Bike Split good for Ironman racing?

Yes. Ironman is a core use case — the database includes the vast majority of Ironman-branded courses worldwide, and the platform models the full 112-mile bike leg accounting for course profile, wind, heat, and your personal power data.

Which bike computers can follow my plan?

Garmin, Wahoo ELEMNT, and Hammerhead Karoo head units can display your Best Bike Split power and speed targets in real time on race day. Some newer Wahoo models are not yet compatible with Power Courses.
