What to wear for a 10K event.


You know how it is, checking the weather 24/7. “Is it going to rain during my run?” “Wait what am I going to wear?!”

If you are training for your first event you might want to start giving some thought to what you will wear on the day. You want to make sure you are properly dressed for the weather conditions and feel comfortable and confident in your choice of outfit. Training in the gear you will race in is definitely recommended. Event day is not the day where you realise that new top you are wearing is giving you unbearable chafe in places you don’t want to be chafing.

It can be a daunting thing to know what to wear during a 10K event, especially when you’ve got 100 other things to think about, you’ve also been given an event t-shirt. Should you wear it? Probably not.

You hear it all the time in the running world. Don’t try anything new on race day and that predominantly means clothing and nutrition. Meaning no new running shoes, no new clothing unless you have worn it a few times and your body is used to the material.

A few things to take into consideration:



Before your event, it is important to get your running shoes professionally fitted by a local running shop for your comfort and your running gait. This means that you can not only train happy but you will be lined up on the start line confident that you have done enough miles in your shoes for them to feel comfortable running 6.2 miles.

Ideally, you want to have your event running shoes about 1-2 months pre 10k, so you can ‘run them in’ and allow the soles of the shoes conform to your feet and become your own.


It is important to bear in mind what the weather is doing on event day because this will determine what you are going to wear. A great rule to follow is to dress for 10 degrees warmer because as you run, your core body temperature is going to increase. You may feel a little cold on the start line because you normally have to stand around for about 10 minutes (depending on the size of the event) but take into account you will soon warm up!


You can also get hotter running in a group of people if it's a large field. Many runners will race in less clothing than they would train in, and choose their race day clothing based on the conditions for that day so always check the weather a few days leading up to the event. You don't want to wake up one spring day and find it's suddenly so much warmer than it has been, your event vest is in the wash and you are unable to wear it!

In relation to what to wear leading up to lining up on the start line, you want to be as comfortable as possible and as you get into your event gear a good rule of thumb is that you should be lightly sweating to know you are sufficiently warmed up.

If the weather is going to be torrential rain and cold winds it’s a different story. It is always worth wearing more layers that you can take off and tie around your waist rather than wearing fewer layers and shivering throughout the whole event and nobody wants that! Layers are always better than a t-shirt and a warm jacket. Here is a great post from Tina Muir on what to wear depending on temperature!


If the weather is reasonably warm, a technical running t-shirt / vest plus some form of shorts, whether that be lycra, standard of capri are ideal. Most of the shorts and many of the T-shirts available now will include a pocket for small essentials, like a car key so if you are travelling alone this may be something to keep in mind.

There are various different lengths of running shorts for your own comfort, these can range from your 2-inch racing shorts to 7-inch longer shorts and many of them now offer built-in lycra shorts. These are great if you do have trouble with chafing, or just want to keep your muscles warmer.

In hotter weather, shorts with an inner brief will feel cooler, rather than lycra shorts but it is important to try out what works for you personally. For women who want a bit more coverage, running skirts or capris tights are a popular and comfortable choice.

Comfort trumps everything when it comes to what you wear on event day, after all, you are going to be wearing it whilst running 6.2 miles (10K).

In cooler weather or rainy conditions, you could look at a long sleeve sweat-wicking t-shirt or a thermal base layer with a lightweight windproof running jacket to go over the top to ensure you are protected from the elements. If you feel like you heat up quite a lot as you run, layers are going to be your best friend.


By event week you want to be certain of what you are going to be wearing come the day of the 10K, whether it's your warm weather day kit or your cold weather. It’s just going to leave you less worried on the day knowing you are prepared and your mind can focus on the miles and remember nothing new on race day!
