Woah woah woah! You could eat your dinner off my bollocks, they are squeaky clean! Under carriage and shorts get a wash after every ride, asap! They do go in at 30 so I will try at 40 as suggested above. Shorts, that is.
Sometimes it’s not practical or possible to get changed as soon as you stop. End of ride pub stops for example. Although I suppose I could take a change in the camelbak and whip em off in the bogs
