I like the idea of 3 races for the grade championships.
Why doesn't HDCC?
It's almost worth changing clubs except HDCC give you a free Giant TCR or Trek Madone (your choice) with every membership renewal.
Also the combined time trial would be good too. I would expect it may take half a day though, unless A & B is one day and C, D, E, F another day. If that happens I will put my order for a time trial bike when I renew my membership with HDCC next year.
