Running briefs to combat chafing!

[ZigZagIntoTheBlue]

I need help! I ran about 6km yesterday and the thigh chafing HURTS! I've literally rubbed my inner thighs raw. Ive got a 5km muddy run on Saturday so I need recommendations for pants/briefs whatever that cover the top thigh area and don't roll up. Extra marks available if I can purchase these before mid week so I can test them before Saturday.

I've tried wearing normal men's pants today but they ride up and the chafed area is still rubbing.
Long term obv I need to lose weight, hence the running, I'm trying!! I'm currently a size 14.

Are you wearing legging to run in? Don't they protect the tops of your thighs?

I wear normal knickers and leggings/shorts from decathlon. What's caused the chafing, were your leggings falling down so a seam was in the wrong place?

I think the saggy granny pants I usually wear were down a bit, I had to keep hoiking them up. I had leggings on over the top but they kept rolling down. I look so glamorous

Leggings/shorts with a drawstring to keep them up. And if they stay up they should keep your underwear up with them!

Runderwear and leggings with a drawstring...

Maybe go commando while you are healing?

I'm size 12 btw so not much smaller. I usually have my shorts pulled right up above my belly button I wear men's tshirts so noone can tell!

Don't wear underwear. Just leggings.

Yep run commando and if need be use Vaseline or sudacream on bits that may rub. Look for running leggings with a gusset like a diamond shaped bit of fabric in the crotch.

I found once I got properly fitting leggings this problem disappeared.

Definitely you need legging with a drawstring pulled fairly tight. Probably helps if the leggings are on the tight rather that loose side.

I run commando, but you need leggings that don't slide down

a) for the pants: Runderwear are the known brand, but they are terrifically expensive. Uniqlo seamless microfibre are pretty much the same thing, as far as I can tell.

b) BodyGlide - best anti-chafe product ever

c) for running shorts: try Decathlon own brand - good kit and easily best VFM

Another vote for commando! I have the decathlon running pants but still chaffe on my bum in winter.

100% never running commando (unless I had to, fire in the swimming pool while I'm changing kind of scenario), however I had my mud run today and wore normal pants with new leggings and it all stayed up much better. At least I didn't flash my arse to the whole course! Thank you all for your advice, I'll look at Runderwear for the next one :)

I have Decathlon running pants.
My second choice is big, stretchy close fitting pants from Morrisons, but I'm sure there are plenty like that around.

I'm a pear shape so need good rear coverage so my derierre doesn't keep eating my undergarments.

Sadly commando is not an option when faced with a sprint finish!

I use victorias secret seemless ones, but more than anything shat halps is plenty of vaseline!
