Let's Talk Boobs

Everyone likes boobs... everyone but ME on a long run.  (Fellas, you have no idea how lucky you are to run shirtless in summer.)

Ever since my long run reached the 16-18-20 digits, I've had major problems around the chest and back.  My long runs end with chaffing, or sweat rash, even sores, around my rib cage.

Chaffing results from friction between the skin and your clothing fabric.  There are three main causes when it comes to the sports bra arena... (source)

1.  Wearing a size too big.  If the band of the sports bra around your rib cage is too loose, it moves on the run.  This friction causes the red rash.  Over great lengths of time (like 4 hour long run!?), the rash can result in an abrasion of the skin.  When you do trunk twists, the band of the sports bra should not move left to right with you.  If it does, you need a smaller band size.  I'm still wearing the same sports bras from 40 lbs ago, so this is probably part of my problem.

Sorry guys, no front views!  :)

2. Trapped Moisture.  The insane heat of this summer is not helping the booby cause either.  After just a couple miles, my clothes are soaked to the bone.  One rule of thumb here... COTTON is the enemy.  Certain fabrics (like cotton) trap moisture, rather than pulling the sweat away from your skin.  That's why many runners also trade underwear for spandex when they run.  Ever have sweat rash on your panty line?  Painful!  You should always wear a sports bra made out of wicking fabric to encourage quick evaporation of your sweat.  My bras are all wicking material, but this crazy summer humidity is pooling sweat faster than it can evaporate.  I'm thinking my only solution is to change halfway through the long run?

3.  Sensitive Skin.  If your sports bra is snug-fitting and moisture-wicking and you're still battling chaffing... you may just have sensitive skin.  You can try the cheap version of petroleum jelly... smear it on your impact spots before the run.  However, petroleum jelly does break down fabrication faster than the advanced, more expensive, products like 2Toms SportShield or BodyGlide.  I've had skin issues all my life, so pretty certain my sensitive skin just adds to the dilemma.  I'm like a tri-fecta here!

Under Armour has been my go-to brand for sports bras, with other $20 versions from Target thrown in the mix.  What is your favorite brand of sport bra??  Please share!  I need to try out some alternatives.

PS. If you ever do get bad chaffing, quick healing is essential!  Try a diaper rash cream.   I had some leftover from the baby days, and was delighted at how wonderful it worked in clearing up the sweat rash.
