How about adding...
25June Snetterton DSC trackday & Desmo Due race
26June Snetterton 8-hour endurance
27June Brands indy
28June Donington GP
29June Cadwell full circuit
30June Mallory park
How are you travelling between tracks? Bikes on trailers, or are you riding between tracks
I would think one set of tyres would just about do those 4 days.
Oh, and Donny to Cadwell is the shortest journey... You'll pass Donny on your way back to Mallory
Crazy idea, but I like it
