How to run a 5km

5km is considered to be a relatively short distance when comparing to other popular running distances such as 10km and half and full marathons.

Whilst there can be tactics used for getting PBs, for most it’s simply about hitting these paces for each kilometre marker and giving it your all and your maximum effort.

As you complete more 5km distances you will gain knowledge of where you start feeling it, how much you have left in the tank, and what your body will find possible.

How long is a 5k?

A 5k race is 5 kilometers or 3.1 miles (3.10686 miles if you want to be precise, but generally it’s rounded down to the simpler measurement).

That doesn’t sound too far does it?

What is the average time to run a 5k?

The average time to run 5km is between 25-40 minutes, but there are a variety of factors that will affect this time such as gender, age, fitness, course elevation, etc. Based on research conducted by RunRepeat.com, to be considered an above-average runner you will need a finish time faster than 35 minutes over the 5km distance, and breaking the data down further the average female runner takes 37:28 minutes and the average male runner 31:28 minutes.

Percentile Male Finish Times Female Finish Times Combine Average Times
1st percentile 00:17:30 00:21:39 00:18:40
10th percentile 00:23:26 00:28:24 00:25:20

Data compiled from RunRepeat.com

When we look into data from parkruns we can see that in 2005 the average finish time for completing a parkrun was 22:17 but in 2020 that time had dropped to 32:30 as more and more runners of a wider range of abilities started taking part. 

Parkrun is very inclusive with a wide range of abilities taking part, so try not to think about parkrun average finishing times as there is so much variation between those finishing first and those at the tailend of the runners.

How many calories are burned running 5k?

The average person will burn around 100 calories per mile, so a 5k should burn off around 300 calories, but the two factors that will impact on this are your weight and your effort put in The heavier you are, the more calories you will expend, and the harder you push yourself the more energy you will need.

If you regularly run 5km or parkruns you will find that your body will become more efficient at that distance and you will burn fewer calories than you used to. For this reason it’s important to mix up your training by adding hill sessions, sprints, longer runs etc.

I only started running at the age of 37, completing the Couch to 5k course, and since then I've been hooked, running 4 times a week and even completing several marathons and an ultra!
