Sub-18 5K: VO2max 56

Running a sub-18 5k takes a running VO2max (VDOT) of about 56.3 and an even pace of 3:36/km (5:48/mile).

If you can already run these, the goal is within reach once you are trained for the distance. Marathon equivalents are optimistic for most runners — endurance, fuelling and pacing matter as much as VO2max (see marathon training and VO2max).

Frequently asked questions

What VO2max do you need for a sub-18 5k?

About 56.3 ml/kg/min of running VO2max (VDOT) if you are fully trained for the distance. Watch VO2max estimates often read a few points differently from VDOT.

What pace is a sub-18 5k?

3:36 per km or 5:48 per mile, run evenly.

What 10K time matches a sub-18 5k?

About 37:20 on the same VDOT model.

Is a sub-18 5k good?

A VO2max of 56 is rated "superior" for men in their 30s and "superior" for women in their 30s on Cooper Institute norms.
