Remember camp as a kid? Take the bare essentials, a bar of soap, you don't really need a wash cloth.Shampoo? if you are using a camp soap it does both, conditioner? are you male or female? If you are male why bother if female then thats another matter. Get one of those shower caddy things you can hang off the showerhead they work really well if you need a lot of stuff. Pack it with sample/travel size toiletries REI has those camp towels that dry really fast, depending on where you park it hang it on your bike and it should be dry in no time. Mostly you just cooling off and rinsing off the sweat. Poof you're done.
