How many miles is a 5k? Your essential guide to running a 5k


How many miles is a 5k? How to train for a 5k? What time should I be aiming for my first 5k? In my blog post this week, I answer these common questions about the 5k.

Whether you’re new to running or new to racing, the first step in your running journey will probably be a 5k.

In my opinion, it’s the perfect running distance as it offers a good mix of speed, endurance and pace.

At 3.1 miles, it’s not a race that you have to train weeks and weeks for, but I’d always suggest you have a base level of fitness before attempting a 5k.

The Couch to 5k programme is a great way to train for your first 5k. If you’ve already run a 5k and looking to get better at it, then check out my intermediate 5k training plan to learn how to run a faster 5k.

How many miles is a 5k

A 5k is 3.1 miles. There’s no doubt that a 5k is by far the most popular distance in the UK and worldwide.

Many runners choose it as their first race distance and go on to complete 10k, half marathon and marathon race distances.

How to train for a 5k

If you’re a beginner runner, the Couch to 5k programme is a really great way to slowly ease you into running.

The programme combines running and walking and normally lasts between 9 to 12 weeks depending on the training plan you go for.

By the end of the programme, you should be able to run for 30 minutes at a comfortable pace without stopping. This is a great place from which to grow and then go onto run your first 5k.

If you’re an intermediate to advanced runner and want to shave some seconds of your PB, there are many ways to run stronger and faster, such as speed workouts, hill workouts and interval training.

These are designed to make you a faster and stronger runner, and when combined with your weekly runs, they have the potential to reduce your race times substantially.

How to run a 5k

How fast you run completely depends on your running experience, fitness levels and your race goals.

To run a sub-30 minute 5k, for example, you will need to be able to run at a pace of 9:40 minutes per mile for the full 5l/3.1 mile distance.

If you’re a beginner runner and your goal is to run a sub-30 minute 5k, this is completely doable. Run at least 1km at 9:40 per mile then build your pace up from there.

To work out how fast you should be running to achieve an even faster time, use a pace calculator. Also check out my post on how to pace your run.

How to prepare for a 5k

Running a 5k is exciting and nerve-wracking all at the same time, especially if it’s your first race.

All your hard work and training will prepare you for race day, but it’s natural to get pre-race jitters.

The best you can do is get a good night’s sleep and try and rest your legs in the 48 hours leading up to your race.

Eat well, stay hydrated and plan your morning before hand so you’re not running around like a headless chicken on the morning of the race.

If you’ve chosen Parkrun as your first 5k, then check out my post on what to expect at your first Parkrun.

How to warm up before a 5k

A warm up is essential for any race, whether it be a 5k, 10k, half marathon or marathon. You need to get your heart racing and blood pumping before the race to prevent injury and loosen your muscles.

For a 5k, a 5-15 minute warm up should be fine. In the warm up, make sure you jog it out and include some dynamic stretches and running drills to get your body ready for exercise.

Parkrun is a great way to experience your first 5k. Held every Saturday morning at 9am across the country, you’re bound to find one that suits your needs. Even better, they’re free and there’s no pressure to run fast so it’s a great event for beginner runners.
