Common half marathon paces

1:30:00 → 4:16/km · 6:52/mi

1:45:00 → 4:58/km · 8:00/mi

2:00:00 → 5:41/km · 9:09/mi

2:30:00 → 7:07/km · 11:27/mi

Pacing strategy

For most runners the safest plan is even splits with a small negative split in the final 5 km. Avoid banking time in the first 5 km — the cost in the back half is far greater than the time saved early on.

Frequently asked questions

What pace is a sub 2 hour half marathon?

About 5:41 per kilometre, or 9:09 per mile. Holding that pace evenly across 21.1 km finishes in 1:59:59.

What pace is a sub 1:45 half marathon?

Roughly 4:58 per kilometre, or 8:00 per mile.

Should I run even or negative splits in a half marathon?

Even splits are the simplest plan and the most common. Slightly negative splits — running the second half a few seconds per km faster — usually produces the best finish time for trained runners.

How do I pace the start of a half marathon?

The first 2–3 km should feel slightly too easy. Adrenaline and a fresh crowd will pull you 5–10 seconds per km faster than goal pace unless you actively hold back.

How do I use a split chart on race day?

Glance at your watch at each kilometre marker and compare against the chart. PocketPacer generates a chart you can keep on your phone or print, with every split spelled out.
