2000m to 3K Conversion Calculator
Stepping from 2000m to 3K shifts the emphasis from sustained aerobic running to tempo and VO2max intervals. Enter your 2000m result and get a 3K prediction that accounts for the increasing aerobic demands at the longer distance.
Quick answer: a 6:40 2000m converts to about 10:26 for the 3000m (typical range 10:09 to 10:48).

How it works
The 2000m to 3K conversion uses Riegel's power-law formula with event-specific exponents, cross-validated by VDOT oxygen-cost modeling. These closely related distances produce highly reliable conversions, typically within 1-2% accuracy. The result includes a confidence range reflecting extrapolation uncertainty.
Training advice
For the most accurate prediction, enter a recent all-out 2000m effort. If preparing specifically for 3K, incorporate tempo and VO2max intervals into your weekly routine. The prediction reflects current fitness — structured training targeting aerobic at ~98% VO2max capacity can help you beat it.
Frequently asked questions
How accurate is a 2000m to 3K prediction?
With a recent all-out 2000m, predictions are typically within 1-2% of actual 3K performance. The close distance relationship provides strong reliability.
What training improves my 3K from a 2000m base?
Focus on tempo and VO2max intervals. Your 2000m provides speed/power that must be complemented with tempo and VO2max intervals. 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.
