I can tell you Mark did 1:45.81 at the Cadwell meet before the last Anglesey coastal, which was when his bike let go on the final stages of the last lap.
I was wondering if there are any Cadwell Park (club) circuit lap times.
I did a meeting last year with Auto 66 and think the club circuit was used on the Saturday, turned a right hairpin before bottom of mountain bends onto start/finish straight and back up copice, took alot of getting used to, lots of lines in and out, I missed it on first lap and went through cones up towards mountain.
