Best Bike Split

Best Bike Split is a specialized tool for cyclists and triathletes that leverages physics-based modeling to optimize race performance. It positions itself as a scientific approach to race planning, trusted by professional teams and over 150,000 athletes worldwide.

The tool's main use cases include predicting finish times before race day, generating precise power targets, training for specific course demands, and executing real-time power guidance during a race. It is extensively used for Ironman events, gran fondos, and professional cycling races.

The target audience is competitive cyclists, triathletes (especially Ironman participants), coaches, and professional cycling teams who seek a data-driven, physics-validated method to plan, train, and execute their optimal race strategy.

• Physics-Based Pacing Plans: The tool uses a math and physics engine to model aerodynamic drag, rolling resistance, gravity, and wind for every segment of a course, creating a personalized variable power plan rather than a generic percentage of FTP.
• Real-Time Race Execution: It integrates with Wahoo ELEMNT and Garmin devices to display your power and speed targets in real-time on your bike computer during the race.
• Comprehensive Course Database: The platform includes a vast database of courses, including the majority of Ironman-branded events worldwide, allowing for accurate modeling with real elevation data.
• Advanced Weather Modeling: Premium plans incorporate forecasted weather conditions, such as wind and heat, into the race plan calculations to improve prediction accuracy.
• AI Workout Builder: This feature allows users to generate customized training workouts based on their race plan and fitness profile.
• Equipment and Strategy Optimization: The tool enables users to simulate how changes in bike equipment, rider weight, drag (CdA), and pacing strategy affect the predicted race outcome.
• Training Integration: Workout plans can be synced to popular platforms like TrainingPeaks, Zwift, and Garmin Connect for seamless training execution.
• Dedicated Coaching Tools: Special subscription tiers allow coaches to create and manage profiles, build race plans, and share strategies for an unlimited number of athletes from a single account.

• Step 1: Create an Athlete Profile: Sign up for a free account and input your personal data including weight, height, FTP, MaxHR, and details about your bike type and components.
• Step 2: Select or Create a Course: Choose an existing course from the extensive database or upload/create a new course file with the specific distance and elevation profile you will be racing.
• Step 3: Configure Race Profile: The system calculates your aerodynamic drag (CdA) and rolling resistance, then combines this with the course data and forecasted weather conditions.
• Step 4: Generate Your Power Plan: The physics engine processes all inputs to output the optimal variable power pacing plan designed to achieve your fastest possible bike split.
• Step 5: Train with the Plan: Use the generated plan to train indoors or outdoors, simulating the exact power demands of your course.
• Step 6: Execute on Race Day: Load the power plan onto your compatible Wahoo or Garmin bike computer to follow the real-time power and speed guidance during your event.

• Proven Accuracy: The physics-based model typically predicts bike split times within 2–3% when input data is accurate, a claim validated by thousands of athletes and professional teams.
• Trusted by Professionals: The tool is used and endorsed by WorldTour cycling teams like EF Pro Cycling, Lidl-Trek, and Canyon//SRAM Racing, lending it high credibility.
• Free Tier Availability: Users can start with a free plan that includes one race plan and basic analytics, requiring no credit card, which lowers the barrier to entry.
• Comprehensive Ironman Support: It is specifically built to model the full 112-mile Ironman bike leg, accounting for course profile, wind, and heat to help athletes arrive at T2 ready to run.
• Strategic Insight Beyond Pacing: It allows athletes to test how different equipment choices, weight, and fitness levels affect their race outcome, enabling smarter strategic decisions.
• Real-World Execution Tools: The direct integration with Wahoo ELEMNT and export compatibility with Garmin devices transforms the theoretical plan into actionable, real-time guidance.

• FAQs: A comprehensive support section with answers to common questions is available on the website.
• YouTube Videos: Instructional and tutorial content can be found on the official Best Bike Split YouTube channel.
• Submit A Ticket: Users can submit a support ticket directly through the website's messaging system for personalized assistance.
• Contact Us: A dedicated contact form is available for inquiries, including API partnership requests.
• BBS Blog: The blog features case studies and cycling strategies that can provide additional insights and usage tips.

• Web application — accessible directly in browser at https://bestbikesplit.com, no download required. The service is primarily web-based, with integration to bike computers (Wahoo ELEMNT, Garmin Edge) for real-time execution.
