Weight Loss Speed Impact

Predict your improved race times from weight loss

If you're looking to improve your running performance and race times, losing non-functional weight can be a great place to start. But how much can you expect to improve your race times? This calculator will tell you.

Enter your current weight, select a recent race distance and enter your finish time. Remember that non-functional weight loss should not include significant loss of muscle mass, so keep up your cross-training and strength work.

Note: Consult with a medical professional before you start any weight management program. Consuming too little energy during intense training may significantly impact your fitness performance and long term health.
