Predict your race times based on a recent performance using proven formulas

📊 Enter Your Recent Race Result

â„šī¸ How It Works

This predictor uses the Riegel Formula and VDOT calculations to estimate your race times at different distances based on a recent performance. The predictions assume:

  • You maintain consistent training
  • Similar race conditions (terrain, weather, elevation)
  • Proper race day preparation and pacing
  • Good recovery and no injuries

Note: Trail races with significant elevation gain will typically be slower than these predictions, which are based on relatively flat course performances. Use these as guidelines, not guarantees!
