I agree with FFF, although perhaps not so strongly.
But I did mine in the same way as FF, I just had a day where myself and a friend flew an aircraft each in realtively unplanned (not unplanned once we knew where we going you understand), but we did not know where to go until the day really. Again it was not meant to be the 300 mile qualifier, it just happened to be.
I went Sywell to Leicester, Leicester to Lydd, Lydd - Le Touquet, Le Touquet Manston and then Manston Sywell via Cambridge O/H....in a Rallye 880 by the way, so it took all day as well.
