I'm riding to Blairgowrie this Friday afternoon, need to be there before 5. Might get train all the way to Frankston, or might ride from further back depending on timing. (Won't be carrying much at least, as someone driving there will be taking my overnight bag.) Will be in Malvern until some time after 12.
On the Sunday I will leave some time after 3 to head back to Melbourne.
If anyone wants to join me any part of the way, either direction, we can make arrangements as to when and where to meet.
