Mile to 10K Conversion Calculator
Convert your Mile performance to a realistic 10K prediction. This tool uses Riegel scaling, VDOT estimation, and critical speed modeling — calibrated for the physiological gap between Mile (aerobic-dominant with anaerobic surge) and 10K (aerobic at 90-95% VO2max).
Quick answer: a 5:16 mile converts to about 38:53 for the 10K (typical range 36:35 to 42:14).

How it works
The Mile→10K conversion blends Riegel's power-law scaling with VDOT oxygen-cost validation. With a 6x distance jump, the predictor applies additional correction factors for the major physiological shift between these events. 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
Use a recent race or time-trial Mile for the best prediction. To reach your 10K target, build tempo runs and aerobic volume progressively. 10K demands specific preparation — your Mile fitness provides the foundation, but tempo runs and aerobic volume closes the gap.
Frequently asked questions
How accurate is a Mile to 10K prediction?
With a recent all-out Mile time, predictions are typically within 4-8% of actual 10K performance. Accuracy improves when the Mile effort is from the past 6-8 weeks under normal conditions.
What training should I do to reach my predicted 10K time?
Focus on tempo runs and aerobic volume. Your Mile fitness provides the speed foundation — building aerobic at 90-95% VO2max capacity through progressive training is the key to hitting the target.
Can I use an old Mile 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.
