A good running bra is important especially if you have large breasts. You’ll want comfort and support so that you can run without thinking about it, and without painful bouncing.
I have tried several and have found that racer back bras are usually too tight and constrictive and makes it harder to breathe.
I want comfort and support without underwire. I want to breathe freely and avoid rude comments and stares from men. It’s an unfortunate factor to keep in mind. It shouldn’t have to be like this, but it is.
There are two bras that I love.
Fiona medium impact, is very comfortable. It’s soft and easy to put on. The straps adjust with velcro in the front and you can easily adjust the fit if you need during your run. I think it gives enough support even though it’s only medium impact.
My other favorite is Under Armour Eclipse Printed High Impact Sports Bra.
The straps can be adjusted so that you can use it as either cross back fit, or regular fit. If you change it to cross back, it’s fantastic. It really holds you in place, prevents bouncing and is very comfortable.
It’s a little hard to put on by yourself, but once it’s on it’s worth it.
