How Does the Prediction Work?

Our race time prediction is based on proven formulas from running experts like Pete Riegel, Jack Daniels, and others. The calculations take into account that pace decreases with increasing distance.

The accuracy of the prediction depends on how well you are trained for the respective distance. For optimal results, your reference race should have taken place within the last 6-8 weeks.

Tips for Improving Your Race Times

Specific Training

Train specifically for the distance you want to race. Marathon training differs significantly from training for a 5K race.

5K: Focus on tempo and VO2max training
10K: Mix of tempo and endurance
Half Marathon: Emphasis on tempo runs
Marathon: Long runs and base endurance

Pacing Strategy

The right pacing strategy can make the difference between a new personal best and hitting the wall.

Start controlled, not too fast
Maintain an even pace in the middle
Try to accelerate in the second half

Recovery and Tapering

Recovery is just as important as training itself. A good taper before the race can significantly improve your performance.

Reduce training volume 1-3 weeks before the race
Maintain intensity but decrease duration
Focus on adequate sleep and nutrition
Don't forget mental preparation
