I admire your persistence to keep trying! Good for you that you went all the way to 3k, op.

My friend always complained about this and now I too understand. It's really painful to deal with, especially walking for that long! I hope you find a product to prevent that. :>

Good Job getting out there. I used to deal with this on top of being hairy and the rub would pull out the hairs adding extra pain. Would also get heckled constantly cause I'd be bouncing around in places that shouldn't bounce. After sticking to it I'm happy to say there is no more bounce. Keep at it. Give your thighs a break and try different things that have been mentioned to prevent or treat the rub and you'll find one that works for you.

Don't feel bad OP, I've been there. That hurts!

deoderant or baby powder helps prevent chub rub. or wear a pair of shorts that are tighter around the thigh so tour skin isn't rubbing against itself.

you tried! I know the feeling. next time, baby powder is your best friend it bandellettes like the comment above said. I hate it when that happens too though.

I've had that problem just remember thick thighs save lives, but a little powder always helps

If that was your limit, it was your limit. There's always next time, and unless there's some rule in unaware of, you can always take a break during the next one and reapply a no-chafe product if need be. Also, 3k is no mere distance- be proud of what you achieved, not ashamed of what you didn't.

You can't walk a couple of miles? Jesus dude..

I'm really glad that this comment section is so overwhelmingly positive in support of OP. Try the workout leggings they sell at Walmart (Danskin Now) The material is perfect for keeping the rub to a minimum.
