Weirdest thread ever. I never stop on a ride and assumed the hanging around at the trail head was for having a breather/chat ect. If your waiting for a gap thats your choice but don’t expect others to join your imaginary queue. If I catch someone, I hang back pass if its safe, but more normally unless the rider in front pulls over I wait untill the end of the section. I’ve been riding trail centre’s since the beginning and never had a problem.
I’ll mention it, if you ride at trail centre’s unless your a riding god sooner or later people will come up behind you. No one’s being rude it’s part of the sport and something you have to get used to, if you can’t perhaps trail centres aren’t the best place for you to enjoy your ride.
