2000m to 10K Conversion Calculator
Enter your 2000m time and get an instant 10K prediction. This tool models the transition from aerobic to aerobic at 90-95% VO2max using Riegel scaling, VDOT estimation, and critical speed analysis.
Quick answer: a 6:40 2000m converts to about 38:37 for the 10K (typical range 36:31 to 41:38).

How it works
The 2000m to 10K conversion uses Riegel's power-law formula with event-specific exponents, cross-validated by VDOT oxygen-cost modeling. With a 5x distance jump, the model applies additional correction factors for the significant physiological transition between these events. The result includes a confidence range reflecting extrapolation uncertainty.
Training advice
Use a recent all-out 2000m from the past 6-8 weeks. To reach your 10K target, gradually build tempo runs and aerobic volume. Your 2000m speed provides the foundation — 10K-specific endurance work closes the gap between prediction and race day.
Frequently asked questions
How accurate is a 2000m to 10K prediction?
With a recent all-out 2000m, predictions are typically within 4-8% of actual 10K performance. The larger distance gap introduces some uncertainty from different energy system demands.
What training improves my 10K from a 2000m base?
Focus on tempo runs and aerobic volume. Your 2000m provides speed/power that must be complemented with tempo runs and aerobic volume. Progressive, specific training over 8-16 weeks can push you past the predicted time.
Should I enter more than one race time?
This page uses your 2000m as the primary input. For a more comprehensive multi-distance analysis, use the full calculator on the homepage — entering 2-3 times produces more precise predictions.
