Sub-1:20 half marathon: VO2max 58

Running a sub-1:20 half marathon takes a running VO2max (VDOT) of about 58.4 and an even pace of 3:48/km (6:06/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-1:20 half marathon?

About 58.4 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-1:20 half marathon?

3:48 per km or 6:06 per mile, run evenly.

What 5K time matches a sub-1:20 half marathon?

About 17:27 on the same VDOT model.

Is a sub-1:20 half marathon good?

A VO2max of 58 is rated "superior" for men in their 30s and "superior" for women in their 30s on Cooper Institute norms.
