bra under bathers

It depends on how much support you require. For my first tri I used a quick drying top that had a built in shelf bra. for me that was fine. some women will wear a sports bra along with a top for more support.

I, personally, would not run in just a swim suit, i need more support than that.

you can wear a swim suit, with or without sports bra. I recommend you try to pick up a cheap pair of tri shorts to wear for the entire race, but you can go swim suit and slip on shorts in transition, but practice this before because it can be difficult to get anything on in transition when you are wet.

whatever you decide to go with, practice before the race.

good luck!

Thanks and I think I will get the tri shorts and wear throughout the race.
