"Health and Fitness" says cycling-specific stuff goes here, so:
Sometimes - but not always - on Audaxes my arse gets badly chafed.
There's a
photo if you are feeling strong stomached. Warning: the image is naturally totally NSFW.
If you are unwilling to look at photos of my hairy behind (and I don't blame you), the chafing extends from the perineum all the way around the anus, roughly along the division between the skin being smooth and hairy and it being wrinkled and hairless, and nearly meets up again about 3cm behind the anus. There's also two less badly chafed arcs outwards from the perineum end towards where I guess my sit bones are.
I'm at a loss to establish what factor causes this to happen. On my one 300 I did not have this problem; on other rides I've been suffering from 150km. Things that don't seem to make a difference (in the sense that I've done them and had both affected and unaffected rides).
Kind of shorts. I've got two pairs each of two kinds of shorts.
Savlon on the bum before the ride.
Being hot and sweaty. On the 300 I sweated pretty extensively coming over the South Downs - I had at least 200km after that to get home, and wasn't significantly affected. I can't, however, say for sure that I've ever been affected on rides in very cold weather.
Any ideas? Anyone had similar damage?
