Mile to 3K Conversion Calculator
Making the jump from Mile to 3K means shifting from VO2max and kick finishing to tempo and VO2max intervals. Enter your Mile time and get a data-backed 3K target that accounts for how aerobic demands increase over the longer distance.
Quick answer: a 5:16 mile converts to about 10:30 for the 3000m (typical range 10:10 to 10:58).

How it works
The Mile→3K conversion blends Riegel's power-law scaling with VDOT oxygen-cost validation. Because Mile and 3K 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 Mile effort from the past 6-8 weeks. If training specifically for 3K, incorporate tempo and VO2max intervals into your weekly schedule. The prediction shows current fitness potential; targeted training can improve it.
Frequently asked questions
How accurate is a Mile to 3K prediction?
With a recent all-out Mile time, predictions are typically within 1-2% of actual 3K 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 3K time?
Focus on tempo and VO2max intervals. Your Mile fitness provides the speed foundation — building aerobic 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.
