Just been reading a pre L2B article from a several times rider in our local rag;
"I'm doing the London-to Brighton, but coming from Holland I'm not used to all the hills, I nearly got up Ditchling last year but people in front of me kept stopping". "I have been mostly training by running because the local roads (2 miles from the route) are far too dangerous to cycle on". "In Holland you don't have to wear a helmet so that will make it much harder"
