Yeah, as far as I remember its about 2.5 to 3 hours, depending on which turnaround point you use. (Some of the group turn at Black Rock, some go on to Mordialloc i think. Doesn't really "get out of the city" rather it follows the bayside suburbs along the infamous "Beach Rd" - favourite haunt of 531 and wattsy and 000's of other dudes. It's a basically flat ride & will probably have a headwind one direction.
