Ride is open to anyone and open to route suggestions but suggest a 6:30am start at BFM, Stromlo and then probably doing a south CCT, then North if time, energy permits.
2 benefit of the CCT loop are (1) if you've had enough or need to leave, it's pretty straight forward to stop and head home (or the cafe/pub), and (2) it's generally not too far to pick up lunch, coffee or water along the way.
I don't necessarily need/want to do the whole thing but would like to get 100-120 kms in, and home early to mid afternoon.
