FitLogic RaceX

The Challenge of Race Execution

Athletes invest months of dedicated training to prepare for race day, yet many fall short of their potential due to poor pacing decisions. Common mistakes include starting too fast and fading, conservative pacing that leaves performance on the table, or failing to account for environmental conditions and course terrain. Even well-trained athletes often struggle to translate their fitness into optimal race results.

RaceX closes the critical data loop between training and racing. It eliminates the guesswork from race execution by providing precise, personalized pacing strategies that account for your unique physiology, current fitness, and the specific demands of your race venue.

Environment Normalization

Our EnviroNorm® technology automatically adjusts your functional threshold values from your training environment to race-day conditions. Temperature, humidity, and elevation differences between where you train and where you race can significantly impact performance. RaceX accounts for these factors to ensure your pacing targets are appropriate for the conditions you'll actually face.

The system even accounts for changing conditions throughout the day. For longer events like IRONMAN triathlons, RaceX predicts how temperature and humidity will evolve from your swim start through your run finish, continuously adjusting your pacing recommendations.

Intelligent Target Identification

RaceX determines your optimal target power and pace based on multiple factors including your localized threshold values, recent training data, predicted race duration, genetic profile, and race-specific conditions. Rather than using generic percentage-based targets, the system calculates the precise intensity you can sustain for your expected race duration.

Course-Specific Optimization

For cycling events and the bike leg of triathlons, RaceX systematically divides the course into power segments based on grade, distance, and other factors. Each segment receives an optimized power target that accounts for terrain, wind conditions, your weight, aerodynamic profile, and overall pacing strategy. This segmented approach ensures you're applying power where it provides the greatest benefit while conserving energy on descents and tailwind sections.

Bike Impact on Run Time™ (BIRT)

For triathlons, RaceX employs our proprietary BIRT technology to optimize energy allocation between disciplines. The system analyzes opportunities to adjust bike intensity when the net effect on total race time is beneficial. Factors including your relative bike and run strengths, body composition, and course profiles all influence how you should distribute effort across the race.

The Science Behind RaceX

RaceX optimization relies on sophisticated race simulation technology that models every aspect of your race performance. The system runs thousands of simulations accounting for your power output, aerodynamic drag, weight, rolling resistance, course elevation, grade changes, wind exposure, road surface conditions, and dynamic environmental factors.

Machine learning algorithms trained on millions of athlete performances continuously refine the optimization models. This vast dataset enables RaceX to identify patterns and correlations that would be impossible to detect through traditional analysis, delivering insights that consistently produce faster race times.

Integration with FitLogic

As a core component of the FitLogic intelligence engine, RaceX seamlessly integrates with other technologies in the ecosystem. It leverages PersonAlign™ for age and gender normalization, draws on Physiogenomix™ genetic insights for personalization, and feeds performance data back to the system to enhance future training prescriptions.

This integration creates a continuous improvement loop where training informs racing and racing informs training. Every workout contributes to more accurate race predictions, and every race provides data that enhances training optimization.

The Only Complete Training-to-Racing System

FitLogic stands alone as the only platform in the world that truly closes the loop between training and racing. While other systems may prescribe workouts or suggest pacing strategies, only FitLogic measures training stress, quantifies adherence through TrainX™ scores, makes precise race predictions via RaceX, and then measures the efficacy of both training and execution to continuously improve its optimization.

This complete feedback loop is what enables FitLogic to deliver measurably better results. Without the ability to predict outcomes and measure effectiveness, other platforms cannot systematically improve their prescriptions. They operate on static philosophies rather than evolving intelligence. FitLogic's unique capability to measure its own efficacy drives continuous refinement, ensuring that every athlete benefits from insights drawn from the entire community's performance data.

Proven Results

Athletes using RaceX consistently achieve personal best performances by executing optimal pacing strategies. The technology eliminates the costly mistakes that plague even experienced athletes, ensuring that months of hard training translate into the fastest possible race times.

Whether you're targeting your first finish or chasing a podium position, RaceX provides the precision pacing intelligence that turns your fitness into performance reality. You've trained too hard to let poor execution rob you of your potential—RaceX ensures your race day delivers on the promise of your preparation.
