I hate H25/2 and H25/8 is A31 yeah? I said I'd not ride that again, though maybe shorter races are ok for ruts. As for being good enough, of course I'm not. Worn out, aged, drunk using cheat courses and money to get times probably fits the profile of quite a few testers though..
The A25/11 is the only other fast course I know of. My 50 PB is on that road.
