It's doable on fixed as both the AAA and ride points count towards it, geared it would be very hard to reach 100 AAA without riding an absolute shit load!
Only the AAApoints count towards the AAA.
The ride points do count towards FWC though, 1pt for each complete 100km.
GMC for example was 7.5FWC, but only(!) 4.5AAA.
Surrey Hills perm (aside from being bloody beautiful at the top of Leith hill last Spring) is 1AAA, but 0FWC.
There's a 100AAA badge? Is there a list for that too?
