In this guide, we look at how to run a faster 5k by discussing the key elements of a successful 5k training plan, including setting realistic goals, incorporating speed and endurance workouts, and proper nutrition and recovery. By following these tips and guidelines, you will be well on your way to achieving your goal of running a faster 5k.

How to run a faster parkrun or 5k
Running a faster parkrun or 5k race time requires a combination of speed and endurance. The first step in being able to run faster and reach this goal is to set realistic and achievable goals for yourself. This could mean aiming for a specific time or improving your personal best.
Once you have set your goal, it’s important to follow a training plan that includes a mix of speed and endurance workouts. Here at Coach the Run we offer a variety of 5k training plans for different levels of fitness. The training schedule comprises interval training, tempo runs, hill repeats, and long runs to enhance both your speed and endurance, preparing you effectively for race day. The 5k is a great distance to focus on as it requires both speed and endurance, helping you improve in both areas.

One of the key elements in training for a faster 5k is incorporating speed workouts. These workouts are designed to improve your running economy, increase your lactate threshold and increase your overall pace. One popular speed workout is interval training, also known as high-intensity interval training (HIIT). This involves alternating between periods of high-intensity running and rest or recovery periods.
Another impactful speed training session involves tempo runs, where you maintain a consistent speed for a prolonged duration. These runs are beneficial for boosting endurance and enhancing your capacity to sustain a quicker tempo. Be mindful of your stride length during these runs.
Build endurance
In addition to speed workouts, it’s important to incorporate speed endurance training into your 5k training plan. This includes longer distances, which are typically done at a slower pace but for a longer distance. These runs help to build cardiovascular and muscular endurance, making it easier for you to maintain a faster pace during the race.
Hill repeats are also beneficial in building endurance as they challenge your leg muscles and cardiovascular system. This type of workout involves running up a hill at a steady pace and then jogging or walking down for recovery before repeating the process.
How to train for a 5k
Proper nutrition and recovery are often overlooked in training for a 5k, but they play a crucial role in helping you run faster. As you increase your training intensity, it’s important to fuel your body with the right nutrients to support your workouts.
Aim to include a balance of carbohydrates, protein, and healthy fats in your diet. Carbohydrates provide the energy needed for your workouts, while protein helps with muscle repair and recovery. Healthy fats are also important for overall health and can help to keep you feeling full and satisfied.
In addition to nutrition, adequate rest and recovery are also essential in training for a faster 5k.
5K speed-building workouts
As mentioned earlier, incorporating speed workouts into your training plan is key to being able to run faster and run a faster 5k. Here are some popular and effective speed-building workouts to try:
Intervals
Warm up with an easy run for 10 minutes, then alternate between 1-2 minutes of high-intensity running and equal periods of recovery. Finish with a cool-down jog for 10 minutes.
Tempo runs
Warm up with an easy run for 10 minutes, then maintain a steady and challenging pace for 20-30 minutes. Finish with a cool-down jog for 10 minutes.
Hill repeats
Find a hill with a gradual incline and sprint up at your maximum effort. Jog or walk down to recover before repeating the process. Start with 5-6 repeats and gradually increase as you build endurance.

How and when to perform the workouts
It’s important to schedule your workouts strategically throughout the week to ensure proper rest and recovery. For example, you may want to do a hard speed workout on Tuesday, followed by an easier tempo run on Thursday, and a long run on Saturday.
Incorporating strength training and cross-training activities such as swimming or cycling can also help improve your overall fitness and running performance.
So, how much low-intensity training should you complete?
Low-intensity training, such as easy runs or cross-training activities, should make up the majority of your weekly workouts. This allows for proper recovery and prevents overtraining, which can lead to injury of muscles or burnout.
A good rule of thumb is to aim for 80% low-intensity training and 20% high-intensity training in your overall weekly mileage. However, this can vary depending on your fitness level and training goals.
5k pace intervals
Pace intervals are a great way to improve your 5k speed and endurance simultaneously. These workout sessions incorporate running at various paces or speeds, pushing your body to adjust to different intensities and boosting your lactate threshold.
Here’s an example of a 5k pace interval workout:
- Warm up with an easy jog for 10 minutes.
- Run at your 5k goal pace for 2 minutes, followed by a recovery jog for 1 minute.
- Repeat this sequence 5 times.
- Finish with a cool-down jog for 10 minutes.
3K pace intervals
For those looking to take their speed and endurance to the next level, incorporating 3k pace intervals into your training can be effective. These intervals are done at a faster pace than 5k pace intervals, which will push your body to run at higher intensities.
Here’s an example of a 3k pace interval workout:
- Warm up with an easy jog for 10 minutes.
- Run at your 3k goal pace for 1 minute, followed by a recovery jog for 30 seconds.
- Repeat this sequence 8 times.
- Finish with a cool-down jog for 10 minutes.
Tempo running
Tempo runs are a key component in building both speed and endurance to improve your 5k. These runs typically involve running at a comfortably hard pace for an extended period of time.
Here’s an example of a tempo run workout:
- Warm up with an easy jog for 10 minutes.
- Run at your target tempo pace (around 80-85% of your maximum heart rate) for 20 minutes.
- Finish with a cool-down jog for 10 minutes.
Threshold intervals
Threshold intervals are similar to tempo runs but involve shorter, more intense bursts of running. These threshold running workouts challenge your body to maintain a fast pace for a longer period of time.
Here’s an example of a threshold running interval workout:
- Warm up with an easy jog for 10 minutes.
- Run at your goal 5k race pace for 1 minute, followed by a recovery jog for 30 seconds.
- Repeat this sequence 8 times.
- Finish with a cool-down jog for 10 minutes.

So, what’s the best hill workout for 5k running?
The best hill running workout for 5k running will ultimately depend on your individual fitness level and training goals. However, incorporating both short and longer hill repeats can be beneficial in building speed and endurance. Here’s an example of a hill workout:
- Warm up with an easy jog for 10 minutes.
- Sprint up a steep hill at maximum effort for 30 seconds, then jog or walk down to recover. Repeat this sequence 8 times.
- Next, find a longer hill with a gradual incline and run at a challenging pace for 1 minute, followed by a recovery jog or walk down. Repeat this sequence 4 times.
- Finish with a cool-down jog for 10 minutes.
How to include strength training workouts in your running schedule
Strength training is often overlooked in running, but it can make a big difference in your overall performance. Incorporating strength workouts 2-3 times per week can help improve the strength of your muscles and endurance, preventing injuries and improving speed.
Here are some examples of strength exercises to include in your routine:
- Squats
- Lunges
- Deadlifts
- Planks
- Push-ups
- Pull-ups
- Bridges
- Lifting weights
Sprint training for a faster 5k
If you’re looking to improve your overall speed, aerobic capacity and running efficiency, incorporating sprint training into your routine can be beneficial. Sprint speed sessions involve short bursts of maximum effort, challenging your body to work at its highest intensity.
Here’s an example of a sprint workout:
- Warm up with an easy jog for 10 minutes.
- Sprint at maximum effort for 100 meters, followed by a 60-second recovery jog.
- Repeat this sequence 8 times.
- Finish with a cool-down jog for 10 minutes.
