Not quite.
If you run 1st Claim for a Fell Only Club, when you join another club you automatically become 1st claim for your 2nd club in the other discplines.
Let me give you some examples
1st Claim Clayton (Fell, Road, XC) 2nd Claim Blackburn H (all except Race Walking) means you can run track 1st claim Blackburn and that is recognised as 1st claim under league rules as they are the first claim Track and Field Club.
But you would be 2nd Claim Blackburn for Fell, Road and XC so could not compete for them other than Track unless the rules of the event allowed it.
1st Claim Bowland (Fell), 2nd Claim Blackburn means that you can run road, XC and track for Blackburn and it is as a 1st claim athlete.
now for a really complicated one :-
1st Claim Bowland (Fell), 2nd Claim Clayton and then another 2nd claim Blackburn.
You would then in effect be 1st Claim :-
Fell - Bowland
Cross Country and Road - Clayton
Track - Blackburn
So you can have 3 clubs as first claim for competition by using the system and I now athletes that do.
I was a bit of an oddball until I was abducted by aliens; but I'm perfectly OK now!
You know yourself WD that as much as your members at Bowland love the club and it's approach to running that members still want to experience running with a team on road or XC (and I think I recall one of yours even venturing on to track once :w00t
But I agree the rules and restrictions on this 1st claim / 2nd claim are just silly and over-complicated which stem from a previous era. They should be changed, but the problem is the people who would be tasked with changing them are probably so out of touch with the reality of our sport that they'd come up with something worse.
