How Long Does a Half Marathon Take?
Most recreational runners finish a half marathon (21.0975 km) somewhere between 1 hour 45 minutes and 3 hours. Where you land in that range depends heavily on training background, and it's worth knowing before you pick a race, since it directly determines which cutoff time you need.
Half marathon finish times by pace
| Pace per km | Half marathon finish time | Runner level |
|---|---|---|
| 4:30/km | 1 hour 35 minutes | Competitive |
| 5:30/km | 1 hour 56 minutes | Strong recreational |
| 6:30/km | 2 hours 17 minutes | Typical recreational |
| 7:30/km | 2 hours 38 minutes | Comfortable recreational |
| 8:30/km | 2 hours 59 minutes | Run-walk |
Most Indian half marathons set cutoffs between 3 and 4 hours, which comfortably covers this full range. A tighter cutoff, closer to 2.5 hours, requires a sustained pace around 7:07/km or faster, worth checking carefully if you're newer to the distance.
What affects your finish time beyond fitness
Course terrain, weather and how well you pace the first half all matter as much as raw fitness. A hot, humid morning can add 10 to 20 minutes to a finish time compared to a cool, dry one at the same effort level. Starting too fast in the opening kilometres, a common first-half-marathon mistake, tends to cost more time in the final 5K than it gains early on.
Training to hit a specific finish time
If you're targeting a specific finish time rather than just finishing, your long runs should include some kilometres at or near goal race pace, not just easy effort throughout. Most training plans build toward this in the final 4 to 6 weeks before race day, after establishing a solid aerobic base earlier in the block. See the first half marathon guide for a fuller training timeline.

Browse half marathonsLooking at how organizers structure half marathon cutoffs on the platform, the median sits right around 3.5 hours, which comfortably covers even a fairly conservative run-walk pace. My honest observation is that a lot of first-timers overestimate how tight these cutoffs actually are and avoid the distance out of caution that isn't fully warranted. If a 3.5-hour cutoff feels tight based on your training paces, it usually isn't. Check the actual number on the category page rather than assuming.
Frequently asked questions
What is a good half marathon time for a beginner?
Anywhere from 2 to 2.5 hours is a solid, achievable target for a first half marathon with consistent training. Finishing is the primary goal; time comes with subsequent attempts.
Can I walk part of a half marathon and still finish in time?
Yes, in most cases. A run-walk approach averaging around 8:30/km still finishes comfortably inside a typical 3 to 4 hour cutoff.
How much slower is a half marathon pace than a 10K pace?
Most runners run their half marathon pace 20 to 40 seconds per kilometre slower than their 10K pace, since it needs to be sustainable for more than double the distance and time.
