I got up to 600 and decided not to go cross country because of the walk and the time. It was really nice to practice getting up and working the lift. I'm retrospect...a small xc would have been fun
I've looked at some flights on xcontest... There have been some long flights from devil's Dyke... I remember one flight ending close to Canterbury. I've seen others which end on the coast at Brighton and newhaven. Admittedly you're not going to break distance records from here, but you can get a decent flight in
