The British paragliding leagues are managed on the https://xcleague.com/xc/ web site. The main National league can be found at https://xcleague.com/xc/leagues/view-1.html. You can get to this years league for Cumbria by going to https://xcleague.com/xc/leagues/view-9.html. If you want to look at previous years, go to the NAtional league page and then use the selection fields. We used to be able to go direct to any league or any year but someone has improved (!) the software on that page.
