Alternative to cancelled Cyclo-cross training tomorrow 4th Oct

Due to travellers on the site at Waterhall cyclo-cross training has been cancelled and replaced by a night ride in Stanmer Park. To take part meet at the A270 entrance [where we normally meet] for a 6:30 departure and ending at 8:00, bright lights are a must have to ride, MTB prefered but cyclo-cross would be ok. To take part you need to be self-sufficient so for some younger riders or incompetent adults this may not be suitable.
