How to Start Running and Prepare for Your First 5K
Summary:
This guide is for anyone preparing for their first 5K. It explains what you need to get started and how to judge an effort you can manage. You’ll also find an example ten-week plan that begins with short runs and walk breaks, then gradually gives you more time running before you cover the full distance.
Getting Started With Your First 5K
Your first 5K can feel like a big step when you are new to running. Five kilometres is 3.1 miles and it may be further than you have ever tried to run before. It is natural to look at that distance and wonder how you will get from where you are now to the finish. The good news is that you do not have to cover anything close to 5K on your first run. You begin with short periods of running and a walk between them. Those walks give you time to catch your breath before you go again. As you follow a plan, you will spend more time running and begin to recognise how much you can manage.
Over the next 10 to 12 weeks, you will generally run three times a week as you build towards your first 5K. Having a day without running between sessions gives you time to recover before you go again. If a week’s runs feel too difficult, you can repeat those sessions the following week before trying longer running sections. This guide includes an example plan to show you how the running sections and walk breaks can change as you progress. When you reach your first 5K, you can run at your own pace and take walk breaks along the way. The aim is to arrive at that distance knowing how to manage your effort and feeling ready to cover it in a way that works for you.
What Do You Need to Start Training for Your First 5K?
You do not need much to begin working towards your first 5K. The early sessions are measured in minutes, so there is no need to map out a five-kilometre route or check how fast you are running. It helps to have a timer for the run-walk intervals and a place where you feel comfortable trying them. If you already have clothes and trainers that feel good to move in, you may have most of what you need.
Running shoes:
Start with trainers that feel comfortable and stay secure on your feet. They should not pinch your toes or rub your heels when you walk. As you begin running more often, pay attention to how they feel during the sessions too. If you are unsure what to choose, trying on a few pairs at a running shop can help you find one that fits well. You do not need to choose a shoe because it is popular or expensive.Clothes you can move in:
A breathable top with shorts or tights will work for many of your sessions. Comfortable running underwear and sports socks can help prevent rubbing, particularly as you spend longer on your feet. Choose clothes that let you move freely and feel comfortable against your skin. On cooler days, remember that you may feel warmer once you have been running for a few minutes.A timer:
Your first sessions alternate between running and walking, so you need a way to know when each part ends. A phone timer or a basic watch is enough. You can set the intervals before you leave if your device allows it. That way, you can listen for the next change instead of looking at a screen throughout the run. You do not need to track your pace to complete these sessions.A place to run:
Choose somewhere you feel at ease, whether that is a path near home or a treadmill. A fairly flat route can make the first few sessions simpler because you will not have to adjust your effort for hills while you learn how to manage your effort. You could run around a short loop and repeat it as needed. There is no need for the route to add up to 5K yet. The early sessions finish when their time is up.Optional ways to track your runs:
A running watch or an app such as Strava can record how long you run and how far you go. Some watches can also show your heart rate, either from the wrist or with a separate monitor. You do not need these tools for the early run-walk sessions or the continuous runs later in the plan. A simple timer is enough for the timed sessions, though a way to measure distance will be useful when you cover your final 5K.
You can add to what you use as your running develops. After a few sessions, you may notice that different socks feel better or that you would rather follow the timings on a watch than your phone. There is no need to work all of that out before your first run. Start with what you have, then make changes when you know what would help you feel more comfortable.
How Hard Should Your Runs Feel?
When you start a running section, begin more gently than you think you need to. You should be breathing faster than you do on a walk, but still able to hold a full conversation while you run. This is often called the “talk test” and it gives you a simple way to judge your intensity without looking at a watch. You might need a breath between sentences, but you should not be struggling to get your words out. If talking becomes difficult, slow down. Your running pace may feel very gentle, particularly during the one-minute runs and that is fine. The aim is to reach the next walk break feeling that you could run again after you have caught your breath. You do not need to make every running section feel difficult for it to help you prepare for 5K.
To help you recognise that effort, let’s introduce your first running metric. It is called rate of perceived exertion, or RPE. It is simply a way to rate how hard running feels to you on a scale from 1 to 10. For these runs, aim for around RPE 3–4. You know you are exercising, but you can keep talking and feel in control of your breathing. The walk breaks will usually feel easier, around RPE 1–2. As the running sections get longer, check whether your effort is rising. If you start at RPE 3–4 and soon feel as though you are working much harder, slow down while you are still running. That adjustment helps you find a pace you can manage for the whole section, including the longer continuous runs later on.

How to Use an Example Couch to 5K Plan
The example plan below shows one way to build towards your first 5K over ten weeks. It has three sessions each week, starting with short runs and walk breaks before moving towards continuous running. You can choose which days suit you, but leave at least one day without running between sessions. For example, you could run on Monday, Wednesday and Saturday. If a week’s runs feel too difficult, repeat those sessions the following week before trying longer running sections. Taking longer than ten weeks to reach your 5K is fine.
Each session starts with a five-minute warm-up walk and ends with a five-minute cool-down walk. The total time includes both of those walks. In the main session, an instruction such as 6 × (1 min run, 2 min walk) means you run for one minute, then walk for two minutes, and do that six times altogether. Take the final two-minute walk before you begin your cool-down. Later in the plan, you will see continuous run, which means there is no scheduled walk break during that running section. If you need one, take it and continue when you feel ready.
Example 10-Week Couch to 5K Plan
-
This week, you will run for one minute and then walk for two minutes. You will do that six times in each session. Start the first minute gently. You should be able to catch your breath during the walk and feel ready to run again when the two minutes are up. All three sessions are the same, so you have a chance to get used to the timings before the running sections become longer.
Run 1
Warm-up: 5 min walk
Main session: 6 × (1 min run, 2 min walk)
Cool-down: 5 min walk
Total time: 28 min
Run 2
Warm-up: 5 min walk
Main session: 6 × (1 min run, 2 min walk)
Cool-down: 5 min walk
Total time: 28 min
Run 3
Warm-up: 5 min walk
Main session: 6 × (1 min run, 2 min walk)
Cool-down: 5 min walk
Total time: 28 min
By the third session, you may have a better idea of how slowly you need to begin. Even if the first minute feels easy, keep enough energy for the runs that follow.
-
You will run for 90 seconds at a time this week, which is 30 seconds longer than in Week 1. The two-minute walks stay the same. Keep your running gentle enough that you can use each walk to catch your breath before the next run. All three sessions follow the same pattern, giving you time to get used to the longer running sections.
Run 1
Warm-up: 5 min walk
Main session: 6 × (90 sec run, 2 min walk)
Cool-down: 5 min walk
Total time: 31 min
Run 2
Warm-up: 5 min walk
Main session: 6 × (90 sec run, 2 min walk)
Cool-down: 5 min walk
Total time: 31 min
Run 3
Warm-up: 5 min walk
Main session: 6 × (90 sec run, 2 min walk)
Cool-down: 5 min walk
Total time: 31 min
Notice how the last run feels compared with the first. If you have to work much harder to finish it, try starting a little slower next time.
-
The first two sessions ask you to run for two minutes, then walk for two minutes. In Run 3, each run becomes three minutes long, but you repeat it four times instead of five. Keep the running pace gentle as the time increases. You should still be able to speak in full sentences during each run.
Run 1
Warm-up: 5 min walk
Main session: 5 × (2 min run, 2 min walk)
Cool-down: 5 min walk
Total time: 30 min
Run 2
Warm-up: 5 min walk
Main session: 5 × (2 min run, 2 min walk)
Cool-down: 5 min walk
Total time: 30 min
Run 3
Warm-up: 5 min walk
Main session: 4 × (3 min run, 2 min walk)
Cool-down: 5 min walk
Total time: 30 min
The three-minute runs may feel different from the shorter ones you have done so far. If you find yourself breathing too hard before the walk break, slow your running down. You are practising staying with the run for longer, not trying to cover more ground in each minute.
-
You begin this week with three-minute runs, the same length you tried at the end of Week 3. Run 2 increases them to four minutes, then Run 3 asks you to run for five minutes at a time. The walk breaks remain two minutes long. As the running sections get longer, there are fewer of them to complete in each session.
Run 1
Warm-up: 5 min walk
Main session: 4 × (3 min run, 2 min walk)
Cool-down: 5 min walk
Total time: 30 min
Run 2
Warm-up: 5 min walk
Main session: 4 × (4 min run, 2 min walk)
Cool-down: 5 min walk
Total time: 34 min
Run 3
Warm-up: 5 min walk
Main session: 3 × (5 min run, 2 min walk)
Cool-down: 5 min walk
Total time: 31 min
For the five-minute runs, give yourself time to settle into the pace. You do not need to feel comfortable in the first few seconds. Begin gently, keep your breathing at a level that lets you talk and use the full walk break before you start again.
-
Run 1 begins with the five-minute runs you completed last week. In Run 2, you will run for seven minutes at a time, with a three-minute walk after each run. By Run 3, you will try ten minutes of running, take a three-minute walk and then run for another ten minutes. You are spending longer on each run, but you still have a walk break before you begin again.
Run 1
Warm-up: 5 min walk
Main session: 3 × (5 min run, 2 min walk)
Cool-down: 5 min walk
Total time: 31 min
Run 2
Warm-up: 5 min walk
Main session: 2 × (7 min run, 3 min walk)
Cool-down: 5 min walk
Total time: 30 min
Run 3
Warm-up: 5 min walk
Main session: 10 min run, 3 min walk, 10 min run
Cool-down: 5 min walk
Total time: 33 min
Take the whole three-minute walk in Run 3, even if you feel ready to go sooner. It gives you time to catch your breath before the second ten-minute run. Begin that second run gently rather than trying to pick up where you left off.
-
The first two sessions still have a walk between longer runs. Run 1 repeats the two ten-minute runs you completed last week. In Run 2, each run lasts 12 minutes. Run 3 is different: after your warm-up walk, you will try running for 16 minutes without a scheduled walk break.
Run 1
Warm-up: 5 min walk
Main session: 10 min run, 3 min walk, 10 min run
Cool-down: 5 min walk
Total time: 33 min
Run 2
Warm-up: 5 min walk
Main session: 12 min run, 3 min walk, 12 min run
Cool-down: 5 min walk
Total time: 37 min
Run 3
Warm-up: 5 min walk
Main session: 16 min continuous run
Cool-down: 5 min walk
Total time: 26 min
Run 3 has fewer minutes of running than the first two sessions this week. The new part is putting those minutes together without a planned break. Start at a pace that lets you talk, even if it feels slower than your earlier runs. If you need to walk before the 16 minutes are up, take a break and continue running when you feel ready.
-
All three sessions this week are continuous runs. The first lasts 18 minutes, the second reaches 20 minutes and the third returns to 18 minutes. You have already tried running without a planned walk break, so you know what the start of a continuous run feels like. This week gives you a little more time to settle into it.
Run 1
Warm-up: 5 min walk
Main session: 18 min continuous run
Cool-down: 5 min walk
Total time: 28 min
Run 2
Warm-up: 5 min walk
Main session: 20 min continuous run
Cool-down: 5 min walk
Total time: 30 min
Run 3
Warm-up: 5 min walk
Main session: 18 min continuous run
Cool-down: 5 min walk
Total time: 28 min
Try not to judge the whole run by its opening minutes. It can take a little time to find a pace that feels comfortable. If you are breathing too hard to talk, slow down while you run. You can still take a walk break if you need one.
-
The first and third runs last 22 minutes. Between them, you will try a 25-minute run. You do not have to run any faster to complete these sessions. Give yourself enough room at the start so that you can keep running as the minutes add up.
Run 1
Warm-up: 5 min walk
Main session: 22 min continuous run
Cool-down: 5 min walk
Total time: 32 min
Run 2
Warm-up: 5 min walk
Main session: 25 min continuous run
Cool-down: 5 min walk
Total time: 35 min
Run 3
Warm-up: 5 min walk
Main session: 22 min continuous run
Cool-down: 5 min walk
Total time: 32 min
If you need a brief walk during one of these runs, take it. You can resume running when your breathing feels more manageable and finish the time you have left. That walk does not undo the running you have already done.
-
You will run for 25 minutes in the first session, then try 30 minutes in the second. The final session returns to 25 minutes. You have already completed a 25-minute run, so this week’s new step is adding five minutes to the middle session. Begin that run gently enough that you can still talk as you get further into it.
Run 1
Warm-up: 5 min walk
Main session: 25 min continuous run
Cool-down: 5 min walk
Total time: 35 min
Run 2
Warm-up: 5 min walk
Main session: 30 min continuous run
Cool-down: 5 min walk
Total time: 40 min
Run 3
Warm-up: 5 min walk
Main session: 25 min continuous run
Cool-down: 5 min walk
Total time: 35 min
You may cover 5K during the 30-minute run, or you may cover less. There is no distance you need to reach in this session. Next week, you will focus on covering five kilometres, with as much time as you need to do it.
-
Your first two runs are shorter this week. Run 1 lasts 20 minutes and Run 2 lasts 15 minutes. Keep both comfortable, then leave at least one day without running before your 5K. For the final session, choose a route where you can measure five kilometres or take part in a measured event such as parkrun.
Run 1
Warm-up: 5 min walk
Main session: 20 min comfortable run
Cool-down: 5 min walk
Total time: 30 min
Run 2
Warm-up: 5 min walk
Main session: 15 min comfortable run
Cool-down: 5 min walk
Total time: 25 min
Run 3: Your 5K
Warm-up: 5 min walk
Main session: Cover 5K at your own pace, with walk breaks whenever you want them
Cool-down: 5 min walk
Total time: Your 5K completion time + 10 min
Your 5K may take longer than any of the timed runs you have done so far. Begin at an effort you can manage and take a walk whenever you need one. Once you feel ready, start running again. Keep going until you have covered the distance, then enjoy your cool-down walk knowing you have completed your first 5K.
Food, Drink and Recovery During 5K Training
Food and hydration are part of the wider picture as someone builds towards a 5K, but there is no single routine that suits every runner. A short run-walk session may feel different from a longer continuous run, especially if it happens at a different time of day. The time since a meal can affect how running feels. People also vary in what they prefer beforehand. The same goes for drinking before or during a session. As the runs change over the weeks, there is an opportunity to notice what feels familiar and comfortable before the final 5K.
Recovery also becomes easier to understand once you have a few weeks of running behind you. Some sessions may leave your legs feeling more tired than others, particularly when the running sections become longer. The days between runs give you a chance to notice how you feel before the next session begins. Your first 5K may take longer than the timed training runs, so the days around it can feel different too. Paying attention to food, drink and recovery during training helps you learn what your own running routine looks like by the time you reach the distance.
What Comes After Your First 5K?
Give yourself time to enjoy finishing. You began with one-minute runs and two-minute walks and you have now covered five kilometres. Think back to how those early sessions felt and what changed as the running sections grew longer. You may have learned that starting slowly makes the rest of a run more comfortable or that a walk break helps you keep going when you need it. Those are useful things to know about your running, whatever distance you choose next.
You can stay with 5K for as long as you like. Running it again gives you a familiar distance to practise, without needing to increase your training straight away. If you would rather work towards a longer run, you can begin extending some of your sessions while keeping the pace comfortable. There is no need to decide on your next goal as soon as you finish. Take a little time to see what you enjoy about running now that the first 5K is behind you. If 10K appeals to you, explore our Beginner’s Guide To Your First 10K to see how you can build from here.
FAQ: Your First 5K
What is a good 5K time for a beginner?
There is no finish time you need to aim for on your first 5K. The time will depend on your running pace and how often you choose to walk. If you would like to record it, treat it as a starting point you can look back on later. It does not decide whether you completed the distance successfully.
Do I need to run 5K in training before my first 5K?
No. The example plan builds up to a 30-minute run, which may cover five kilometres for some runners and less for others. Your final session is where you cover the full distance. You can use walk breaks if it takes longer than your training runs.
What should I eat before my first 5K?
Choose food you already know sits comfortably before a run. You can use one of your later training sessions to find out whether you prefer a meal with plenty of time before running or a smaller snack closer to the start. Your first 5K is not the day to experiment with an unfamiliar breakfast.
Can I do other exercise while following a Couch to 5K plan?
Yes, if you feel comfortable doing it alongside your running. Walking or another activity you enjoy can fit on days without a run. Pay attention to how your legs feel before the next session. If an extra workout leaves you too tired to complete your planned run, give yourself more time to recover or make that activity gentler.
Final Thoughts
Your first 5K begins long before the day you cover the full distance. It starts with those one-minute runs, when you are learning what pace feels manageable and getting used to heading out again a few days later. As the sessions change, you may notice progress in small ways before you notice it in distance. A run that once felt long becomes familiar. You find that you can slow down when you need to and keep going. Those moments matter just as much as the final five kilometres.
When you reach your 5K, give yourself credit for the work that brought you there. You may run the whole way or take several walk breaks. You may finish feeling strong or find the last part harder than you expected. None of that changes what you have done. You started with running in short sections and worked towards covering a distance that once seemed a long way off. That first 5K belongs to you, however you complete it.
