Deciding what to wear for a half marathon can be overwhelming – and surprisingly complicated. With so many options, it’s difficult to know what running clothes and gear you will actually need on race day.
Finding the perfect half marathon outfit will not only boost your confidence on race day, but will help you perform your best and stay comfortable. Add on some helpful gear and you’ll be able to refuel, hydrate and avoid any unnecessary pain.
How to decide what to wear for a half marathon?
Your ultimate decision will depend on a number of factors, such as the weather, location, altitude, type of race, etc. The first thing to consider when selecting a half marathon outfit is the weather. A hot, humid race day will warrant a very different selection than one that is cold and snowy.
The type of running shoes you select will depend on whether it’s a trail or road race, and many of your gear and accessories will depend on the amenities offered at the start and throughout the course.
Once you’ve narrowed down the type of running clothes and gear that you’ll need, you’re ready for the fun part: picking your outfit and deciding exactly what to wear for the half marathon.

As you begin the process of deciding what to wear for a half marathon, it can be helpful to narrow down the basics. Here are the essential pieces every runner needs, regardless of their climate or skill level.
Half Marathon Outfit
