Definitely don't let 33s put you off, I did it last year with a group on a pair of gravelking sk 32s and rode a day and a half in the wet - one guy rode 28s but was severely limited by clearance and didn't have access to another bike. Yes, some sections were difficult and a few unpassable for all of us due to rain but a lot of it was extremely enjoyable. As others have mentioned, SDW was tough on the flint-laden descents, as were the overgrown rutted tractor paths on hillsides (mostly in Wiltshire). We took three days and that included an 'easy' day plus a number of mechanicals...have a great time!
