Did it today! Very hot, and hard work, but made it round. Solent ATC seemed pretty miffed that we didn't know where we were going at the next waypoint, but Bristol thought it was funny.
It was a tad frustrating that I didn't know how accurate we had to be...was it a town, a housing estate or a particular building (say a church)?
It was fun all the same, but I doubt if I'll get a prize based on the scratchings we made on the waypoint sheets.
Good lcuk on your attempt.
