You've been putting in the training for months, building up your distances and stamina and as your first triathlon approaches you may be wondering, what do I wear? Can I wear the same workout clothing that I've been wearing throughut my training? Is there anything that I need to wear/have with me during the race that I haven't had during my workouts?

This quick guide is going to cover all of your triathlon outfit options.

What Should You Wear in Your Triathlon?

During your training you will most likely have been wearing activewear like gym leggings, shorts, sports bras and vests.

However, when it comes to the race day, your options need to be updated. Many choose to wear a tri-suit which has been specifically created for a triathlon. A tri-suit is made using a hydrodynamic, swimsuit like fabric. It also has padding in the crotch area which is much needed for the bike, however it's not as thick as standard bike short padding so that you don't feel uncomfortable whilst your running.
