Time Trial / Time Trialling / TT

I don't have any support so a 24hr is probably a bit too much.
A 12hr might be doable without too much reliance on others, hence the interest.

Options:
CC Breckland B12/3 on 8th Aug
WCTTCA & LTTCA Champs D12/1 on 22nd Aug
ECCA (inc. VTTA Champs) E2/12 on 22nd Aug
Kent CA Q12 on 5th Sep

You have probably missed the closing date for the CC Breckland?

There is a thread on the testers forum about riding 12's unsupported and general consensus is it is doable depending on the circuit.
