Are there any groups doing early morning weekday rides?

I sadly have to work weekends and some weekdays, but when i can I love to go for a ride before work mainly at Manly Dam. So far iv been pretty much riding on my own and as nice as the serenity is I feel with a group id me more inclined to push my self harder. Are there any other riders or riding groups that do regular early morning rides that finnish by 8:30? I would love to start joining some groups to meet other riders and advance my riding.
