What to Wear for Running: The Essentials

A practical guide to running clothing: fabrics, fit, socks, sports bras and what you can skip.

You do not need expensive kit to run, but a few choices make it more comfortable.

Fabric

  • Choose technical fabrics such as polyester or merino wool, which move sweat away from the skin.
  • Avoid cotton for longer or colder runs, as it holds sweat, becomes heavy and can chafe.

Fit

  • Clothes should be snug but not tight, and move with you.
  • Flat seams reduce chafing.
  • Shorts or tights should stay in place without riding up.

Socks

Good socks prevent blisters. Choose moisture-wicking socks that fit snugly without bunching. Avoid cotton socks.

Sports bras

For those who wear them, a well-fitting sports bra with good support makes running far more comfortable. Fit is individual, so try different styles.

Weather layers

  • Hot: light, loose top and shorts, cap
  • Cool: long sleeves, perhaps gloves
  • Cold: base layer, mid layer, windproof jacket, hat and gloves
  • Wet: a light waterproof jacket

Visibility

In low light, wear reflective or bright clothing and use lights.

Carrying things

  • A running belt or armband holds your phone and keys.
  • A small waist pack holds water and snacks for longer runs.
  • Shorts with pockets are enough for many people.

What you can skip

  • Expensive branded gear
  • Compression clothing, unless you like it
  • New kit on race day

Tips

  • Try clothes on a short run first.
  • Wash technical fabrics according to the label.
  • Replace worn-out kit.
