5K Training Plan

Are you new to running, or perhaps returning to running after a break from fitness training? Beginner or not, completing a 5K race is a great way to get into running. There are hundreds of 5K events happening all over the UK, which is great news for fundraisers and fitness enthusiasts alike! Whatever your reason for running a 5K, your best chance of preparing for race day is by following a training plan.

Although a 5K is a relatively short distance at 3.1 miles, it is still important to train beforehand, not only to help you improve your running time and fitness levels but also to avoid injuries before you cross the finish line. 

How long does it take to train for a 5K?

In honesty, this will vary from person to person. You’ll need to consider a few factors such as your current fitness level, your goals (whether you’re aiming to beat a certain time or just cross the finish line) and of course, how much time you actually have before race day to train.

Whether you are a beginner or an experienced runner, there are a number of training schedules you can follow to help you build up to your race. The number of weeks covered in a training plan will usually determine how much you can expect your fitness level and running time to improve before your event. For example, if you only have a couple of weeks to train you probably won’t have enough time to transform into the next Usain Bolt!  

A training plan can help to keep your training fun and engaging, as well as increasing your fitness level. Below, we explain some of the different 5K training programme lengths and what you can expect to achieve by following one.

Training for a 5K in 4 weeks

As we mentioned before, 4 weeks probably won’t be enough time to make any radical transformations to your fitness level, especially of you are new to running, but it should be enough time to build up your confidence with running for longer periods of time. 

Being a fairly short amount of time, a 4 week training plan will assume that you can already run for around 5 minutes or more comfortably. The training plan will start you out with 3 training sessions a week of around half an hour, which will consist of a combination of running and walking. The following weeks will focus on incorporate more time focused on running and fewer minutes of walking in between. Although it is recommended for total beginners to spend more than 4 weeks training, if you are running out of time before your race it is best to focus on building up your distance rather than your speed, and aim to train at least 3 times per week, whether running, walking or doing a combination of both.

Training for a 5K in 6 weeks

If you have 6 weeks to go before your 5K, you have a good amount of time to build up your fitness before you take on that 3.1 mile run – even if you are a total beginner. As with most training programmes, a 6 week programme will start out with easier runs, with intervals of running and walking, and build the length of running time and distance over the 6 week course. By the end of the training programme you should be able to run comfortably for 30 minutes.

Once you have crossed the finish line of your first 5K you may then want work on your speed, and maybe even aim to complete the whole 5K run in 30 minutes. If you are an intermediate or more experienced runner, already running several times a week, following a 6 week plan should help you to focus your training, if you feel that you need more of a challenge you could incorporate more uphill runs into the plan.

Training for a 5K in 8 weeks

If you have 8 weeks to spare before you lace up your running shoes on race day, you’ll have a good amount of time to train, especially if you follow a structured plan! An 8 week plan is designed to build you up from slower run walk workouts to comfortably completing a 5K course, even If you are just starting out with fitness and currently don’t run at all.

If you are a more experienced runner, you might find the pace and increase in intensity over an 8 week period to be a little slow. Adjust the training plan to be more challenging by varying your pace or adding in intervals where you run at a fast sprint for a few minutes at a time. Doing hill sprints will also have the effect of strength training and make for a more challenging workout.

Training for a 5K in 10 weeks

10 weeks is ample time to get yourself up to speed with running a 5K! For a total beginner you have enough time to build up from walking and jogging for short periods of time, to being able to run over 3 miles without stopping. For more experienced runners hoping to achieve a new 5K personal best, 10 weeks will give you plenty of time to work on your pace and shave off those all important seconds.

The initial weeks will focus on building up your running distance with shorter, easier runs with periods of walking, and then build up the distance you cover each week. Towards the end of the 10 week programme you should be able to complete steady runs for at least 30 minutes. You may also be looking at increasing your speed and challenging yourself to lower your average running time by the end of the programme.

Round up

Generally, the earlier you can start training the better – especially if this is your first 5K race. Before you begin any new training plan it is best to seek advice from a qualified medical professional. Once race day comes around, make sure to pace yourself throughout the course and drink plenty of water.
