Saturday Bike Ride - All paces welcome

This is a weekly ride that a group of cyclists and skaters do on Saturday mornings.
We meet around 9:15 am and roll off is at 9:30 am.
The course is a 1 mile loop with no lights, so nobody gets dropped if they can't keep up with the pace of the group.
It's only a 1 hour workout. People will do between 20 to 30 miles.
You can come with a any kind of bike. Ideally a road bike.
