3200m to 5K Conversion Calculator

Convert your 3200m performance to a realistic 5K prediction. This tool uses Riegel scaling, VDOT estimation, and critical speed modeling — calibrated for the physiological gap between 3200m (aerobic) and 5K (aerobic at 95-100% VO2max).

Quick answer: a 11:30 3200m converts to about 18:41 for the 5K (typical range 18:11 to 19:23).

How it works

The 3200m→5K conversion blends Riegel's power-law scaling with VDOT oxygen-cost validation. Because 3200m and 5K 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 3200m effort from the past 6-8 weeks. If training specifically for 5K, incorporate threshold and tempo sessions into your weekly schedule. The prediction shows current fitness potential; targeted training can improve it.

Frequently asked questions

How accurate is a 3200m to 5K prediction?

With a recent all-out 3200m time, predictions are typically within 1-2% of actual 5K performance. Accuracy improves when the 3200m effort is from the past 6-8 weeks under normal conditions.

What training should I do to reach my predicted 5K time?

Focus on threshold and tempo sessions. Your 3200m fitness provides the speed foundation — building aerobic at 95-100% VO2max capacity through progressive training is the key to hitting the target.

Can I use an old 3200m 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.
