What is a good finish time for 5K, 10K, half marathon and marathon?

A good finish time depends on who is running: your age, your sex, how long you have been training and the course on the day. The bands below give a rough sense of where different kinds of runner tend to finish, so you can set a target that fits you.

Rough time bands by distance

These ranges are broad guides drawn from general experience of UK races. They are not official statistics, they are not averages, and plenty of runners fall outside them in both directions. The bands overlap in real life, and age and sex shift them considerably.

What the three columns mean

• First-timer finishing comfortably. Someone who has followed a beginner plan for a couple of months or more and gets round steadily, perhaps with some walking. Finishing is the achievement. The time is a starting point to improve on.
• Regular runner. Someone who has been running three or four times a week for a year or more, has done the distance before and trains with some structure.
• Club runner. Someone who trains most days, includes speed sessions and long runs, and races often. The quicker end of this band is competitive at local races.

Elite and national level runners are faster again and sit outside this table altogether.

Why one number never fits everyone

Age and sex

A time that is ordinary for a 28-year-old man can be outstanding for a 62-year-old woman. This is exactly what age categories and age grading are for. Comparing yourself with your own category, or looking at your age grade percentage, is far more informative than comparing with the whole field. See running age categories explained for how both work.

The course and the weather

A flat, sheltered road course on a cool, still morning can be several minutes quicker than a hilly or off-road one, even over 10K. Heat, strong wind, mud and crowded narrow sections all cost time. A slower result on a hard course may be a better run than a personal best on an easy one.

Training background

Improvement is quickest in the first year or two. A new runner can take many minutes off a 10K time in a season, while someone with ten years of training may work hard for a few seconds. Both are doing well.

Better ways to judge your time

1. Against your own previous times. A personal best is the clearest sign of progress, and it is measured on chip time for most runners. See chip time vs gun time.
2. By category position. Finishing in the top half of your age group is a sound first goal, the top quarter a strong one.
3. By age grade. A single percentage that allows for age and sex, useful for tracking form over many years.
4. By how you ran it. Even pacing, with a second half close to the first, usually means you judged the effort well. A big slowdown suggests the start was too fast.

Setting a realistic target

The most reliable guide to what you can run is a recent time over a shorter distance. Put a 5K or 10K result into the race time predictor to get an estimate for a longer race. Treat predictions for the marathon with some caution, because they assume you have done the long runs to match.

Once you have a target, the pace calculator will turn it into minutes per kilometre or mile, so you know what the effort should feel like in training. Many runners find it helps to set three goals for race day: a best case if everything goes well, a realistic target, and a fallback such as simply finishing strongly.

How to get quicker

For most people the gains come from consistency, not from heroic sessions. Running regularly for months, building distance gradually, adding one faster session a week once you have a base, and arriving at the start rested will move you up the table. Our training plans set this out week by week for each distance, starting with the couch to 5K plan for complete beginners.

Whatever the clock says, remember that everyone in a results list trained, turned up and covered the distance. A good finish time is one that reflects the work you were able to put in, and gives you something to aim at next time.
