Sub-2:15 half marathon pace

To run a sub-2:15 half marathon you need to average 6:24 per kilometre — 10:18 per mile, 9.4 km/h — and reach halfway in 1:07:30. Sub-2:15 sits between finishing and racing: a long run of 16–18 km and one steady session a week usually gets it.

The fitness behind a sub-2:15 half marathon

A sub-2:15 half marathon is a VDOT of about 31.7. The same fitness, trained for each distance, runs:

5 km29:19 (5:52/km)
10 km1:00:56 (6:06/km)
Marathon4:37:26 (6:34/km)

So a 10 km in about 1:00:56 is the clearest sign you are ready. If your recent 10 km is well slower than that, the goal is still on — it needs a block, not a hopeful race day.

Training paces for it

Easy7:20–8:21/km at the coast · 7:57/km or slower in Johannesburg
Threshold6:15/km · 6:46/km in Johannesburg
Intervals5:39/km · 6:07/km in Johannesburg

At altitude

The same fitness is slower high up. Raced at about 1 680 m, a sub-2:15 half marathon effort comes out near 2:25:37; to break 2:15:00 up there you need fitness worth about 2:05:09 at the coast. Gauteng runners chasing this time are best off choosing a coastal race.

Common questions

What pace is a sub-2:15 half marathon?

6:24 per kilometre, or 10:18 per mile.

What 10 km time shows I can run a sub-2:15 half marathon?

About 1:00:56 — the same fitness, trained for that distance.

How fast should easy runs be when training for a sub-2:15 half marathon?

No faster than 7:20/km at sea level, or 7:57/km in Johannesburg. Slower is fine.

Can I run a sub-2:15 half marathon in Johannesburg?

It is harder: at around 1 680 m the same effort is about 8% slower, so you need fitness worth about 2:05:09 at the coast.

How long does it take to train for a sub-2:15 half marathon?

It depends on the gap. Improving about 0.4% a week is a reasonable rate for a trained runner, so a 5% gap is roughly 12–13 weeks. The plan page works it out.
