Hey Charles, if you're keen for some company the Samford Velos are a nice bunch of mature riders & sit on a good average speed. There are two groups--earlier/ faster, half hour later/slower. They have a website (link below) which covers all the info to save me dribbling on. Anybody is welcome & rides vary from 35km up to about 120km (average 50km). Their summer departure time is 5.30am or 6.00am for the second group.
They leave from the Samford Patisserie every Saturday morning & the ride calender will give you the destination. They do venture over your way & climb Mt Cootha or now due to Gap Creek Road being recently sealed they've included a loop to the Western Freeway bike path.

Gas propulsion.......it's natural don't fight it.
