2014-07-19 (Sat) - LFGSS CC London Velodrome Day

I've booked a taster session for before (April), so assuming that is sufficient.

Nope, that's just stage 1 of the 4 stage qualification procedure.

See this just above your post:

Trying to organise accreditation for this is a nightmare. I will almost have to take 4 days off just to sort it out

Would be nice if there could be a single 2 hour session to get people used to riding other tracks through all 4 stages on one day, instead of throwing people with years of experience at HH etc. in with total noobs.
