Anyone can ride.
We tend to be two groups, the Mid Essex crowd based in Witham and its environs, and Auntie Helen and myself, plus anyone else ho wants to come along. AH and I meet most Thursdays somewhere between our abodes (Colchester / Southend) and we ride slowly (rarely do we average over 11 mph) and occasionally we meet with others on Saturdays for "WARTY" rides. Our rides tend to be punctuated with tea and cakes, and pubs for lunch.
The Witham crowd's activities are mostly nocturnal and they too like to visit pubs.
