The best running shorts are the ones that disappear after the first kilometre. They stay where you put them, don’t ride up, don’t chafe, and keep you comfortable whether it is a cool morning loop or a warm evening run.
Because running repeats the same motion thousands of times, small details show up quickly: a waistband that slips, a seam that rubs, a fabric that holds sweat. This guide covers what to look for when choosing running shorts for women in the UK, so you can find a pair that suits how and where you run.
What to Look for in Running Shorts
Length and fit
Shorter shorts give the most freedom of movement, while longer lengths and bike-short styles cover more and reduce thigh friction. There is no single right length. Choose the one that stays put when you stride and feels comfortable when you sit, stretch or climb stairs afterwards.
Lining and chafing
Inner thigh rubbing is the most common complaint on longer runs. Two things help: a built-in lining or snug inner layer, and flat, soft seams where your legs meet. If you often chafe, bike-short styles that sit close to the skin are worth trying.
Waistband
A wide, flat waistband is usually more comfortable than a thin elastic one, and it stays in place better. A drawstring lets you adjust the fit for longer runs when your body temperature and movement change.
Pockets
Even a small pocket is useful for a key, card or gel. Check where it sits and whether it stays flat when you are carrying something, as a poorly placed pocket bounces.
Fabric
Look for lightweight, moisture-wicking, quick-drying fabric with four-way stretch. For clothing worn against the skin for long stretches, it is also worth checking the product page for the fibre content and finish. Recycled fibres are a good sign, and you can read more about chemical finishes in our guide, Are Gym Clothes Toxic?
A quick checklist before you buy
- Does the waistband stay in place when you jump and stride?
- Is there a lining or snug inner layer?
- Are the seams flat where your legs rub?
- Is there somewhere to carry a key or card?
- Is the fabric moisture-wicking and quick-drying?

Care Tips for Running Shorts
- Wash after every run, as sweat left in the fabric breaks it down faster.
- Use a cool wash, and skip fabric softener, which reduces wicking.
- Air dry where you can. Quick-dry fabrics dry fast anyway.
Key Takeaways: Choosing Running Shorts
- Choose a length and fit that stay put when you stride, not just when you stand.
- A lining or snug inner layer and flat seams reduce chafing.
- A wide waistband and a small pocket make longer runs easier.
- Moisture-wicking, quick-dry, four-way stretch fabric is the baseline.
- Check the fibre content and finish on the product page.
Running Shorts FAQs
What length running shorts are best?
It depends on how much freedom and coverage you want. Shorter lengths move most freely, while longer and bike-short styles reduce thigh friction. Choose the length that stays put when you stride.
How do I stop my thighs chafing when I run?
A lining or snug inner layer and flat, soft seams help. Many runners find a closer bike-short fit more comfortable on longer runs.
Can I run in bike shorts?
Yes. A close fit that stays in place, with moisture-wicking, quick-dry fabric, works well for running, especially on longer distances.
How should I wash running shorts?
Wash after every run on a cool cycle, skip fabric softener, and air dry where you can to keep the fabric wicking well.
