1500m to Mile Conversion Calculator
Both 1500m and Mile demand a unique blend of speed and endurance. This predictor uses your 1500m result to estimate Mile potential by modeling how your aerobic with strong anaerobic finish capacity scales across middle-distance events.
Quick answer: a 4:50 1500m converts to about 5:14 for the mile (typical range 5:08 to 5:22).

How it works
The 1500m→Mile conversion blends Riegel's power-law scaling with VDOT oxygen-cost validation. Because 1500m and Mile are relatively close in distance, the conversion is highly reliable — typically within 1-2% accuracy. Where both distances fall within aerobic range, critical speed modeling adds a third reference point. The result is a predicted time with a confidence range.
Training advice
For accuracy, enter a recent all-out 1500m effort from the past 6-8 weeks. If training specifically for Mile, incorporate VO2max and kick finishing into your weekly schedule. The prediction shows current fitness potential; targeted training can improve it.
Frequently asked questions
How accurate is a 1500m to Mile prediction?
With a recent all-out 1500m time, predictions are typically within 1-2% of actual Mile performance. Accuracy improves when the 1500m effort is from the past 6-8 weeks under normal conditions.
What training should I do to reach my predicted Mile time?
Focus on VO2max and kick finishing. Your 1500m fitness provides the speed foundation — building aerobic-dominant with anaerobic surge capacity through progressive training is the key to hitting the target.
Can I use an old 1500m time for this prediction?
Recent times (within 6-8 weeks) give the most reliable predictions. Older results may not reflect your current fitness, especially if your training has changed significantly.
