fenders, wool, showers pass jacket, rainlegs, wool cycling cap.
ibex knickers if it is cooler, ibex bib shorts if warmer. a thin woolie layer for under the jersey.
if it is warm i'll leave out the jacket. here is a blog post from a wet, solo 300k:

if its going to be cold - i'll try to address fingers and toes. toes are easier - waterproof socks from sealskinz - not 100% waterproof - but do hold in the heat. shoe covers can work. fingers are going to get wet, regardless. haven't been able to do anything about it other than try and keep them warm if it is cool...
