When I started running long distances, I had to stop buying cheap, cotton sports bras and started buying ones made of nicer fabric that were actually made for running. RunningWarehouse.com has a great sale section.

Not much you can do about it after the fact - if you give it a few days, the rubbed skin will dry out, probably scab over, and stop hurting. On really long runs or runs in the rain, I like to apply BodyGlide to my skin under the straps and bottom band of my sports bras.

Usually get this after 2 hour+ runs. I got nothing for you lol

I've started to get cuts on my boobs. I tried body glide and it didn't help. I'm buying a new sports bra. I'm hoping that will help.

I went through a LOT of sports bras before I found one that doesn't chafe, so I bought about 8 of them. Even so, I get a red line if I'm going ~15+. Moving Comfort destroyed me. It's really unfortunate that it's a trial and error thing, since they're so expensive and there's no way you can return a bra that you've run in for 2 hours.

BodyGlide helps but doesn't totally solve the problem for me. You can also take chapstick or a mini tub of vaseline with you and apply midway through.

^This. I started having chafing problems training for my first half. I bought one designed for running and was lucky that the first one worked for me (Moving Comfort Fiona). I ran my half with no chafing. Like someone else mentioned, this one hooks in the back. I did start getting chafing again once it started to wear out.

Body glide is my best friend for long runs. I swear I have three or four "bottles" of it laying around the house. I also second the moving comfort Fiona...LOVE LOVE LOVE it.

Is there any chance you are losing or gaining weight? Even losing weight could be the problem, if your boobs and ribs aren't holding the band in place anymore.

My sports bra recently started chafing me so bad! Today was horrible. I have a big red line across the front of my ribs where the band was. Its painful to touch right now, it feels like a sunburn. It looks my bra tried to cut me in half! A few days a similar thing happened except the band had actually slipped up and chaffed my boob instead of my ribs. I'm not sure why this is happening to me, its never happened before in the past. All of my bras are the same brand, model and size. They aren't that old either, like they aren't stretched out or anything. This just started happening this past week and I'm not sure what has changed other than I slightly upped my milage. Does anybody else have this problem? How do I prevent chafing? Also, is there something I can do to make this feel less horrible in the meantime?

1) Are you wearing a correct bra? You mentioned you bought 3 new ones based on your previous experience. However if you have bought same size and if meanwhile you have either gained or lost weight around chest area you probably want to look into it.
2) If you are wearing correct fitted bra, apply body glide prior to run
3) For already aggravated and chafed skin apply a good Coconut Oil at night prior to sleeping and wear loose tee. Let the chafed part of the skin breathe
4) When selecting a Coconut Oil please, please read the ingredients. The only ingredient it should have is "Coconut Oil".

IMHO the best bra for women for running is Moving Comfort which anyway you are using. However here is my little experience - I wear Moving's Vixen and there was this just one, just one bra that I bought that just won't fit. Turns out that entire manufactured lot was defective. This is just one time that it has ever happened for me in my "relation" with Moving Comfort.

EDTA : Moving Comfort recommends Maia (has a hook behind) or Vixen for C and Ds.

Yep, the same thing happens to me. It's the 1 thing that I dislike out of the 100 amazing things about the bras I get. I just use vaseline for anything longer than an hour and slather it all over my underboobs and ribcage where the bottom of my bra goes. (Note: I also use gratuitous vaseline on my feet and inner thighs, and I am mostly chafe/blister free for months now.)

Yeah this also happened to me when I lost some weight. The girls were bouncing more and bam - so much pain. I bought new bras (same model) in a smaller size and no more major problems. I aquaphor around any places that have been hot spots in the past before long runs. Also taking off your bra ASAP after a workout is helpful.
