Until recently I have been a trail rider except for an occasional charity ride. I would borrow a Road bike and enjoyed the crew. Last Fall I picked up my first skinny tired bike of my own since the 70's This old dog is learning a few new tricks, but needs some help.

The last few weeks there have been a couple times when I pass a group. I always give them a greeting and go my way. (many people pass me, some say hi, some are focused and ignore me.) A few minutes later a couple riders from the group I pass will pass me and then look to see where I am. Is this a friendly challenge? Should I give chase? Did I violate some code? What should I do?
