WOW, this post is old. Sorry I didn't see it earlier. I lead a group ride (when I'm not on duty) every Saturday morning. We start in Knightstown on the square, just off Highway 40. I don't know where you are from but we welcome everyone that wants to ride with us (on a road bike). Our mileage just depends on who shows up for the ride and how much time we have to ride but it usually is usually between 30 and 50. Our pace varys depending on who is there also, its not a competitive ride and we don't drop anyone. If a group pulls ahead of everyone else then we will stop after a while and let everyone catch back up. We have a consistent 3-5 but have had as many as 8. We run an ad in The Banner which is the local Knightstown news paper.
Oh yea, we start at 8:00am on Saturday mornings.
I am probably the fastest rider in our group and I maintain an average of about 19mph for a 50 mile ride. For the last couple Saturday's we have averaged about 17 for 35 miles. None of us are professional riders, just a group of people who like to ride.
