Joined the club for their 40 mile ride this morning. Skies were overcast, temps in the 70's and humidity levels quite high. The ride takes in two of the famous parks in Louisville. As you exit the first park there is a stop sign at the bottom of the hill. Riders make a left onto this main road. As I came down the hill and neared the stop sign (quite often blown by riders) I heard riders ahead of me call "car right, car left". I announced I was stopping. At the bottom of the hill I did just that, looked left and then looked right. The next thing I know I'm being pushed forward - I was rear ended by another rider! He hit me really hard. Thank goodness I had unclipped. First words out of my mouth were "son of a b*****" followed by you can't run a stop sign. He tried to tell me he wasn't going to blow the stop sign and had been trying to stop (I don't believe him given how much momentum he transfered into me and my bike). Needless to say I was not a happy camper. Thank goodness neither of us was injured (I'm going to have a whopper of a bruise on my left hip and right arm) and neither bike was damaged. It appears those of us who follow the traffic laws are even at risk of being hurt by our fellow cyclists. The remainder of the ride was fine but my hip is pretty darn sore. All I can do is shake my head over this incident.
