Ask most runners what's on their training plan for the day, and "easy run" will come up more often than you might expect. It's not a cop-out or a rest day in disguise – it's actually one of the most important sessions you can do. But if you're new to running, the term can feel a little vague. How slow is slow enough? How long should you go? And why does it matter so much? Here's everything you need to know.
The humble easy run works harder than it looks. For starters, it's one of the best ways to build aerobic capacity and endurance over time – the kind of quiet, steady progress that compounds into real fitness. It also plays a crucial role in recovery and injury prevention. If you've been training hard for weeks or have just completed a long run, an easy run keeps your muscles flexible and stiffness at bay, rather than letting everything seize up. And for beginners especially, easy runs lay the foundation for everything that follows. Building a solid aerobic base early on is what makes real improvement possible – you have to earn the harder sessions.
Easy running delivers both short and long-term physical benefits, including improved recovery, cardiovascular fitness, and musculoskeletal resilience.
During an easy run, your body primarily relies on slow-twitch muscle fibres – the ones recruited during lower-intensity exercise. These fibres are rich in mitochondria and myoglobin, an oxygen-binding protein that releases oxygen to keep you fuelled and moving. Because you're working at a comfortable effort, your breathing stays steady and controlled, allowing for a consistent oxygen supply to those fibres.
This brings us to a key training principle: the 80/20 rule. Around 80% of your training should be low-intensity – easy runs and similar efforts – with the remaining 20% at a harder intensity. It's a simple but powerful framework that many runners swear by. In practical terms, that typically means three to four easy runs per week, depending on how often you're training overall.
One of the more social perks of this type of run is that you can actually hold a conversation whilst doing it. Whether you're heading out with a friend, a family member, or your run club, it's the perfect opportunity for a catch-up – no gasping required.
Your pace should feel genuinely easy – comfortable enough to chat without straining. And whilst it can be tempting to compare yourself to a friend or a running influencer, try to resist. What feels easy varies from person to person, so focus on your own effort rather than someone else's numbers.
As a rough guide, easy runs typically sit around 60–90 seconds per kilometre slower than your goal race pace. If you don't have a race pace to work from yet, don't worry – the perceived effort and heart rate guidance below will steer you in the right direction.
In terms of duration, easy runs can range from around 20 minutes up to an hour or more, depending on your fitness level and where you are in your training. If you're just starting out, 20–30 minutes is a perfectly solid place to begin. If you're building towards a marathon, your easy runs will naturally extend over time.
If you're brand new to running, it's perfectly fine to walk when needed. If you're feeling tired or nursing an injury, listen to your body and ease off.
Your Rate of Perceived Exertion (RPE) for an easy run should sit around three or four out of ten – effortful enough to know you're moving, but comfortable enough to breathe and talk freely. For a deeper dive into RPE, check out our guide.
Not got a GPS watch? No problem. The simplest low-tech check is the talk test: if you can speak in full sentences without pausing for breath, you're at the right effort. If you're struggling to get more than a few words out, slow down.
You may have come across the term "Zone 2" – but what does it actually mean? Zone 2 refers to working at roughly 60–70% of your maximum heart rate: there's effort involved, but conversation remains easy. Our ambassador Ethan breaks down Zone 2 in detail in this article, including how to use it to get more from your easy runs. A running watch is a handy tool for keeping yourself in this zone, so it's worth considering if you haven't already invested in one.
Going too fast.
It's tempting to push the pace, but the whole point of an easy run is steady, sustainable effort. Resist the urge to sprint.
Ignoring how you feel.
Running apps and training plans are useful, but they don't know how you're feeling on a given day. If you're genuinely exhausted, don't attempt anything strenuous – pushing through fatigue is one of the quickest routes to injury.
Skipping your warm-up and cool-down.
Even on an easy run, it's worth spending a few minutes on dynamic stretches beforehand – leg swings, hip circles, and high knees all help to prepare the body for movement. Afterwards, a gentle cool-down with some static stretching will help your muscles recover and reduce soreness ahead of your next session.
Here's a quick breakdown:
Easy run
A regular fixture in your weekly schedule, used to build endurance and aerobic fitness over time.
Recovery run
Done specifically after a tough session or event – a marathon or ultramarathon, for example – to keep you moving whilst your body recuperates. It's shorter and even more relaxed than a standard easy run.
The key distinction is intent: easy runs are a consistent part of your training; recovery runs are reactive, used when your body needs something especially gentle after going hard.
Running improves with consistency. Like any discipline, regular training leads to real progress. Weave easy runs into your weekly schedule, factor in rest days, and don't be afraid to vary your routes – it keeps things interesting and your body adapting. Over time, you'll likely find that what once felt like a challenging easy pace starts to feel genuinely comfortable. That's not a sign to push harder straight away; it's a sign that your fitness is growing. Enjoy it.
