Chafing happens when skin rubs against skin or fabric rubs against skin. Lots of moisture, such as sweat or rain, make chafing even worse.
When I chafe, it’s under my sports bra band or under my arms where tank tops tend to rub my skin. I have scars from sports bras cutting into the skin under my boobs, so I definitely know how painful chafing can be. It is not fun!
1. Know what clothes trigger the chafe and avoid them. I have one tank top that I love, but it’s a little baggy and whenever I wear it, it chafes underneath my armpits. Always. Maybe it’s time to get rid of it…
Moisture-wicking clothing is a life saver when it comes to chafing. Wearing the appropriate gear to keep yourself dry will help you avoid chafing. Stay away from cotton. Cotton and chafing do not mix. Cotton bad.
2. Find some type of lubricant/cream that works for you. I swear by BodyGlide for Her and Jake loves Chamois Butt’r. Ever since I started using Body Glide, I haven’t chafed! I never start a run without slathering some on under my sports bra band. It’s a life saver. And when I race or have a run over 10 miles, I put it on the backs of my arms and under my armpits. It helps SO much. I used to wear a chest strap heart-rate monitor under my bra band, but it would cut into my skin and slice it. I tried the BodyGlide with it, but it didn’t help, so I just stopped wearing it. If anyone has tips for dealing with that, I’d love to hear them!
When Jake is racing (he runs ultras, so he’s out there a LONG time), he slathers Chamois Butt’r on every time he sees his crew. Legs, groin, arms…everywhere. We just know that in addition to his food and hydration, we need to have a bottle of Chamois Butt’r out. Dry skin tends to chafe more than moisturized skin, which is why these products help! They also create a protective layer between skin and skin or skin and fabric.
2. After you shower, pat your skin dry, don’t rub.
3. Once you’re dry, put something on the chafed areas. I like to use coconut oil, but you can also use Destin or other diaper rash creams, or even a lotion like Aquaphor. The more moisture the cream has, the better.
4. Avoid tight clothing while your skin heals. Putting a tight shirt on after I’ve chafed the crap out of my rib cage and armpits is hell.





Body Glide is a life saver! Inner upper thigh chafing is the worst!
A cheap alternative to some of the more expensive products is Vaseline.
Downside is that it tends to be messier!
