How Predictions Work

Data Sources

Race data collected from official Ironman race calendar and individual race pages. Environmental data based on historical weather patterns for race locations. Elevation profiles sourced from official course maps and athlete reports.

Prediction Algorithm

Your predicted finish time is calculated by:

Establishing base times from your input metrics
Adjusting for course elevation (bike and run)
Adjusting for environmental factors (temperature, humidity, altitude, wind)
Adjusting for technical difficulty and terrain
Comparing against historical race averages when available

Suitability Rating

Each race receives a suitability score (0-100) based on how well it matches your strengths:

Swim Match (15%): Compares your swim ability to race swim conditions
Bike Match (45%): Evaluates your power/climbing vs course elevation
Run Match (30%): Assesses your run pace vs course difficulty and heat
Environment Match (10%): Considers your preferences and tolerances

Accuracy Disclaimer

Predictions are estimates based on available data and typical conditions. Actual race performance depends on many factors including: training progression, race day conditions, nutrition execution, pacing discipline, mechanical issues, and unforeseen circumstances. Use predictions as a general guide, not a guarantee.
