What to Wear for a Marathon or Half Marathon

Putting in all those miles of training is, of course, a big factor in reaching the finish line of a marathon or half-marathon. But it can be just as important to get the right running gear.

Avoid trying new things at the last minute. Ideally, your shoes, clothing and accessories will all have been tested for a period of time, so you don't have any surprises with your marathon or half marathon gear; especially if this is your first marathon! 

If something has worked in training, it will also work in the race. Above all, whatever you wear on race day must be something you're comfortable in. Keep an eye on the weather conditions and make sure you have a couple of options if it’s an unexpectedly hot, cold, windy or rainy day.

So, what are the 10 must-haves for marathon & half-marathon runners? With this simple checklist, we hope to get you race-ready and flying through the finish line with a smile:

1. Running Shoes

In case you've suddenly realised that your current shoes have done way too much mileage than they should have, or they're causing you some problems, check out our Natural Gait Analysis service. We'll make sure your shoes are still the right type for you and won't bring you any surprises on race day. If you can't make it to our London store, we also offer Online Gait Analysis.

Running Socks

2. Running Socks

Runners don't always realise how important it is to have a pair of proper running socks. If you think an old pair of regular socks will do, you may find yourself having to stop to adjust them a few times during a race, or even end up with a few unwelcome blisters. To keep your feet comfy, fresh and blister-free throughout the race, we recommend you invest in a pair of technical running socks. Here are some of our top picks:
