Well for those still crazing for another round the bay fix here is your answer
The guys I ride with on Sat out west have organised an Audax version of around the bay, departing Bicycle Superstore at Hoppers Crossing at 7:00am. Total ride distance is 204km heading back roads to Geelong first.
The enrty cost is $5 insurance then pay your way on the ferry (all up about $20 + food).
No Westgate Bridge but you do get to go on the Westgate Punt!
Should be about 50 riders all up so no crowds to deal with - contact Russell direct on the above link if your up for it
