I know you have to set guidelines, but I think the organisers should be able to exercise some discretion.
I've done PPP and Sedbergh Hills twice so would qualify, however, I think this amount of climb over such a short distance would be too much for me.
Hopefully not by the end of the year
So I would say 2 x AL in last 2 years, or a demonstrable ability to cope with such an event.
