did it 2 years ago, not sure I'd do it again
it's an experience, all human life is there for sure, some huge fat girls on utter scrap heaps with flat nobbly tyres, everything
the downside was fairly narrow lanes getting choked with riders, people stacked now and then and brought the whole thing to a standstill for an hour, M25 stylee, if you can avoid the masses I gues it''s good, I see now why people were setting off at the crack, we were off fairly promptly
as said, every single hill, no matter how gentle had people pushing, often blocking the road, it was very very hard to ride up Ditchling for the people using the entire width of the road to push up and telling people calling for some room to ride up to **** off, nice
