How to Deal with Chafing From Sports Bra When Running

You Asked: Chafing and Running

You're asking and I'm answering . . .

"Dear Fit,
I love to run, but I have a hard time running consistently, because after a run of a decent length (30 minutes or longer), I often find that the skin below my breasts has been chafed by my sports bra. This makes running painful for about the next 4 days. Do you have any suggestions of a good sports bra that might cut down on my chafing? I am, for good or ill, a D cup.

I feel your pain and chafing can be the worst! There are many things you can do to help prevent this and to see them just


Chafing is caused by the combination of rubbing and sweating, so wearing good gear that wicks the sweat away is really important. You want to avoid cotton at all costs. I talked to a bra expert at Title Nine sports and she recommended two bras for this situation:

  • They Dynamic Duo ($39): Not only do I love the name of this bra since it is designed to prevent the unflattering uni-boob, but the underwire in this bra is placed between two layers of fabric. The inner layer is great for wicking and this bra is recommended for women with D cups too!
  • Three Reasons Support ($44): If you are looking to avoid underwire, this bra is a great choice. Also lined with wicking fabric, this bra is designed to support D cups for high impact activities like running.

You should avoid cotton shirts and run in a well fitting top made of wicking fabric as well.

Another preventative measure is lubricating the areas that get chafed. This problem is so common there are products out there to help. Body Glide is designed to prevent blisters and chafing and it now includes 25 SPF. You could also check out Runner's Lube. Good old fashion Vaseline has been a stand by for years too.

It is important to treat the chafed sore like an open wound to promote healing. Wash and clean the sore with antiseptic to prevent infection, then cover it with a sterile gauze pad to allow the area to breathe while it heals.

Staying properly hydrated, especially on long runs, is key, too. It is important that the sweat doesn't dry and crystallize, which can increase the odds of chafing occurring.

Sure do hope this helps!
