Best Sports Bra for a Triathlon

Best Sports Bra for a Triathlon

One of the things I remember most about my first Triathlon, wasn't the hardcore training or trying to borrow a bike (since I didn't own one at the time), it was trying to find a sports bra that I could wear swimming, cycling and running!

It amazed me how difficult it was to find something that could transition without any fuss and provide great support while being comfortable for my G cups!

A high-impact tri bra is an essential piece of equipment. It’s as important as the rest of your gear and it has the potential to either slow you down or greatly enhance your performance.

The changing environment and different activities make this sport unique and puts a greater demand on your clothing. Your tri bra, like the rest of your triathlon clothing, must seamlessly transition from swimming to cycling to running. This means that it has to be fast-drying, moisture wicking, form-fitting and lightweight yet supportive.

So what type of sports bra should you wear in a triathlon?

  1. It’s important that your triathlon bra can go from one discipline to the other without fuss and preferably, one you can wear for all three sports.
  2. Quick drying, sweat wicking and breathable fabric is a must as you don't want to be cycling or running in a wet sports bra!
  3. It goes without saying your tri bra needs to support you while doing high impact activity like the run but also allow for movement while swimming.

How should a sports bra fit?

  • A sports bra should have a firmer feel than your normal bra and the firmness should come from the elasticity of the fabric, not from the bra being tight. Fabric with firm elasticity will allow you to move and breathe while still keeping everything comfortably in place.
  • The bottom band of a sports bra should be horizontally level front to back (if the back rides up, the bra is either too big or the straps are too tight). In bras with separate cups, the centre piece should lie flat on your breastbone.

  • If the bra is dividing your two breasts into four (i.e., there is extra skin coming over the top of the bra or hanging out of the sides), go up a cup size.
