What to wear running, whether you're a seasoned pro or just starting out.

Whether you’re a seasoned jogger or are taking your first tentative steps towards a 5K, we’ve broken down what to wear running.

Comfort, of course, is key. The best leggings are ones that won't inch down as your miles clock up, and the best sports bras ones that don't niggle or dig in. Anything that restricts your movement or needs to be adjusted every couple of paces just won’t do. 

Remember - whatever you're wearing, running has huge benefits for your physical and mental health. It's been proven to help people beat depression, and can even lower the risk of an early death.

What to wear running

A supportive sports bra

There are two key terms that crop up when shopping for sports bras - compression and encapsulation. Referring to the way in which the bra supports your bust, compression styles draw your breasts close to your body, while encapsulation holds them in two separate cups. The former normally looks more like a crop top, and the latter like a higher coverage take on your day-to-day bras.

Compression bras should be enough for smaller busts to enjoy running bounce-free, but if you’ve been blessed with a bigger bust you’ll need one that boasts encapsulation. Some styles mix both together, for even better support.

Reliable trainers

Not all trainers were created equal, and the type you need will depend on your running gait. In layman's terms, that’s how you move and land your feet as you run.

There are three different categories: normal pronation, under pronation or over pronation. Too much under or over pronation and you run the risk of injury, so it’s worth taking the time to get this analysed for your perfect pair of trainers. Shops like Runner’s Need offer this as an in store service.

The best running shoes for women will have a generous helping of cushioning and support, both of which will deplete as you wear them. For this reason, experts recommend you change your trainers after every 400 miles. A word of warning though - make sure you wear in any new trainers before a long run - your toe nails will thank you for it.

Technical fabrics

Figure-hugging lycra is the runner’s fabric of choice for a reason. Sitting close to the body, it works like a second skin to keep you cool when it’s hot, and warm when it’s cold. Sweat-wicking fabrics take this to the next level, helping to draw moisture away from the body, so you stay nice and dry.

What to wear running in the summer

Running in the summer tends to be a balancing act of wearing as little clothing as possible, while steering clear of a wardrobe malfunction or pesky chafing.

It’s in warmer weather that sweat-wicking fabrics really come into their own, keeping you cool instead of uncomfortably clammy. They make light work of sweat patches too.

For a simple summer running get-up, start with a form-fitting vest top and lycra shorts that end just below above the knee. If that’s showing more skin than you're comfortable with, you can always layer an oversized t-shirt or a pair of breezy, baggy running shorts on top.

What to wear running in the winter

The weather tends to become more unpredictable during the winter months, so even if your app promises glorious sunshine, it’s good to think ahead.

Layers are key here. The one closest to your body should fit nice and snug, trapping heat and keeping your chest warm.

If you’re worried about catching a chill, add a jacket into the mix. A waterproof one with taped seams will prepare you for all eventualities. Your hood might not stay up while you're running, but you’ll be grateful for it as you wander back from your cool down.

Winter is not the time for shorts, unless you want to end up with wind-whipped legs, of course. Opt for full-length leggings tucked neatly into snuggly running socks.

It’s much darker during the winter months, so make sure you stay both safe and seen with a light reflective kit. Most running jackets and trainers feature glow-in-the-dark strips as standard, but you can always add more if need be.

How do you carry your phone while running?

While there’s no reason why you can’t simply run with your phone in your hand, it does increase the risk of a smashed screen should you take a tumble. To keep your device safe, look for a pair of sporty bottoms with a handy pocket.

Alternatively, look for a phone holder that straps onto your upper arm or waist. If you find these tend to slip and slide when you’re pounding the pavements, a specialist, elasticated vest could be the solution for you.

Go-to brands when buying running attire for beginners


Often overlooked in favour of more sports-focused brands, H&M is our go-to for affordable activewear. You might expect it to sag and bag after a couple of wears, but we can report that they not only wash well, but stand the test of time too.The collection isn’t currently available in all of their stores, so for the full range, you’re best to browse online.
