WHAT IS INTERVAL TRAINING
Interval training is key for improving your running speed over these shorter distances, as these sessions push you to run at faster paces than you would probably be able to race at. Interval training helps teach our nervous systems to run faster with adaptations that come with the faster-paced running. Not only does it push you to run a faster pace due to the shorter distances, but it also allows you to train your neuromuscular system to run with good form while you are running the interval.
Interval training leads to a lot of physiological changes throughout the body. It allows your body to build up more of a tolerance to lactic acid (That burning sensation in your legs when the going gets tough!) and increases your cardiovascular efficiency which is the ability to deliver oxygen to your working muscles.
WHAT TYPES OF INTERVAL TRAINING ARE THERE?
There are endless types of interval training sessions that you can do, but all of these can be sorted into short rest, medium rest or longer rest sessions. Each has its own benefits and can be beneficial for improving over shorter distances.
Shorter rest interval sessions should be implemented when you’ve already built some form and you’re close to race day. I would typically run these kinds of sessions the month leading up to a 5K/10K race. Think of these as sharpening sessions, honing in on the pace you’ve built up over the past few weeks.
Medium rest intervals will typically be used when you are looking for race-specific fitness. A lot of the interval repetitions are going to be at target 5K/10K race pace so you can get used to how the pace feels and if you need to adjust your planned race pace in any way leading up to the race.
Longer rest intervals will be used when you are early in the training plan for your race. These sessions take a little longer to recover from because you’re running that much harder during them. To allow for this, you’re getting longer recoveries to make up for it whilst running the session. These longer rest periods allow you to run the reps at close to an all-out effort. With these type of sessions, quality is very much the priority instead of the number of repetitions, so ensure that you're running with the best form possible.
ARE INTERVALS JUST FOR THE ELITE?
In short, no. interval training for shorter races can suit every single runner, from beginner to elite.
This doesn’t mean to say that you should start training like the elites, however. It’s very easy to fall into the trap of trying to copy what some of the professional runners do to ‘FastTrack’ your fitness, but this is only a recipe for disaster - they’ve had years to adapt for their specific interval sessions, and you jumping right in at the deep end would likely lead to injury.
Instead of trying to train like the elite, learn from them instead
Interval training can be very important for those that are just getting into running that can’t quite achieve the race distance. Their limit, for example, may only be 6 minutes of running in total before they need a rest, and interval training can come into play by training you to run for just that little bit longer with the breaks in between.
SOME OF MY FAVOURITE INTERVAL TRAINING SESSIONS TO TRY
400m repeats: 10 x 400m at predicted 5K pace with 90 seconds walk/jog recovery between each interval. This type of session will help you get used to running at your predicted 5K pace and allow your body to adapt to it. 400m may not seem like a long distance to run, but when you’re on those last few reps, running at predicted 5K personal best pace does get quite difficult!
6 x 1 mile cut down with 90 seconds recovery: This session will feel easy to begin with but it soon creeps up on you. That’s why it is such a staple session when building for a 5/10K race. It teaches your body to run hard under fatigue and lactic build-up. Start off at a pace you think you can hold for around an hour (your threshold pace) and build to 5K pace or faster, you’re carrying fatigue but you will be more than capable of finishing the session!
10 x 200m with 3-minute recovery: All at 5k pace or faster. This kind of session is not going to feel like an all-out session, and you should feel pretty good after finishing it. It’s more about building your neuromuscular engine. What I mean by this is running with efficient form, not over-striding to reach a high pace, and keeping a strong controlled posture. None of the efforts should leave you completely breathless but have your 5K race in mind when you’re doing this kind of session.
Intervals are a staple session for anyone that is looking to improve over the shorter distances, by implanting them into your training week you are likely to see improvements to your shorter races. When you are building them into your week be sure to structure them in so you are getting enough recovery around your long run and life in general!

Mental Preparation for Race Dayby Marcus Sladden / Oct. 14, 2020
Race day will find most runners wracked with nerves. You’ve done the miles - prepared your body in every way you can. But when you’re standing at the start line, your most valuable asset is your mental state. Your ability to conquer overwhelm, claim any nerves and push those pain barriers when they arise will make all the difference between getting a PB or dropping out before the finish line.
The Right Shoe is Key for Trainingby Marcus Sladden / Oct. 13, 2020
Every runner is different. We all have a unique gait made up of so many factors. Our cadence, the way our foot lands as it hits the pavement, and the way we carry our weight are a few of many things that determine our individual running style.
How to Cool Down for Runningby Marcus Sladden / Apr. 13, 2020
The cool down for running is to tell your body that you have stopped exercising. Allowing your heart rate to slow down and your muscles to return back to normal. It also provides a good mental transition from running harder to the end of your session.
How to Practice Mindful Running and Why is it Important?by Marcus Sladden / Jan. 28, 2020
Mindful running is the art of keeping your mind in the present whilst on the run. A thing that is very easy to do when you are running. Especially if you are running solo. You’re not dwelling on the past or worrying about the future, but rather focusing on what you’re doing, whether it’s cooking dinner, working on a project, running on cross country paths, or writing an email.
Why Training Slower Can Make You Race Fasterby Marcus Sladden / Jan. 21, 2020
We're going to answer the question of why training slower can make you race faster. A lot of runners think that if they run fast they are going to be fast, whilst this is right in so many ways there is such a thing as going too fast, too often which leads to injury, burnout and fatigue.
HOW TO SET GOALSby Marcus Sladden / Oct. 30, 2019
Knowing how to set running goals can be a daunting task. Having a running goal, however big or small, can help you to keep focused and motivated as a runner. Your running goals should remain personal to you and relevant to your own training targets.
GOOD RUNNING HABITS TO BUILD INTO YOUR TRAININGby Marcus Sladden / Oct. 30, 2019
On average it takes around two months to form a habit or 66 days to be exact. Good running habits are so important to us runners, especially when it comes to injury prevention and looking after our bodies so that is just too long to wait. Here is a break down five good habits to add to your training now which will make you a better all-round runner.
