1:50 half marathon pace at a glance
A 1:50:00 half marathon works out to 5:13 per kilometre or 8:23 per mile over the full 21.0975 km (13.109 miles). In speed terms that is 11.51 km/h or 7.15 mph — the setting you would use on a treadmill for a race-pace session.
Because every GPS watch over-measures a little in a big-city race, many runners aim a few seconds per kilometre faster than 5:13 — around 5:10/km — to leave a small buffer for weaving and wide corners. Pace yourself by the official markers rather than your watch average.

What fitness does a 1:50:00 half marathon require?
Using the Daniels & Gilbert VDOT model, a 1:50:00 half marathon corresponds to a VDOT of 40.4. These are the equivalent performances at other distances — times you should be capable of if you are equally well trained for each:
| Distance | Equivalent time | Pace /km | Pace /mile |
|---|---|---|---|
| 1 Mile | 7:03 | 4:23 | 7:03 |
| 5K | 23:55 | 4:47 | 7:42 |
| 10K | 49:37 | 4:58 | 7:59 |
| Half Marathon | 1:50:00 | 5:13 | 8:23 |
| Marathon | 3:47:50 | 5:24 | 8:41 |
Intermediate level
This goal suits runners with a year or more of regular training. One quality session a week (tempo or intervals) plus a long run, with everything else easy, is usually enough to get here. Runners aiming for this time typically train around 35–55 km (22–34 mi) a week, with a weekly long run of 90 minutes to 2.5 hours depending on the race distance. Treat these as general ranges, not prescriptions — the right volume for you depends on your history, age and how well you recover.

Key workouts for this goal
These sessions, built from the paces above, are staples of training for a 1:50:00 half marathon. Include one or two quality sessions per week, always with an easy warm-up and cool-down.
Cruise intervals (threshold)
3–4 × 1.6 km (1 mile) at 5:03/km (8:08/mi) with 60 s jog recovery.Raises the pace you can sustain before lactate accumulates — the engine of every race from 5K to marathon.
VO2max intervals
5 × 1000 m at 4:39/km (4:39 per rep), 2–3 min easy jog between.Improves your maximal aerobic capacity; each rep should feel hard but controlled.
Goal-pace blocks
Within a long run: 3 × 3 km at goal pace 5:13/km (8:23/mi) with 1 km easy between.Teaches your body and brain exactly what race pace feels like on tired legs, and lets you rehearse fuelling.
Easy long run
Run at 6:41–6:04/km (10:45–9:46/mi).Long, easy running builds the endurance that keeps your pace from fading in the second half.
Race-day tips
- First 5 km at goal pace or slightly slower: around 26:04–26:19.
- Settle in from 5–15 km: this is where the race is won — steady rhythm, relaxed shoulders.
- One gel is plenty for most: take it around 8–10 km if you use one, with water.
- Push from 18 km: the last 3 km is where a negative split pays off.
