There is the possibility to do a full FAI triangle 750k out of Parham (
PAR,OSW,BRN) but it would be a major acheivement, although last Friday I
reckon it was do-able! Free distance seems the easiest way.

In the UK what is the proceedure for declaring a free distance attempt in
such a way to allow claiming distances over 500km? Is this actually
possible? Is it possible to do a UK 750 diploma on a free distance flight?
How about a 1000? ( Apart from the obvious problems of the weather and
sufficient damnd space to do it in that is )

Do you make out a declaration form that says - 'I'm off to do a free
distance'?
