When we did our first Cycle Oregon many years ago we were instructed by ride officials to say "On your left" as we passed slower riders.
We developed the habit of saying this every time we pass slower riders. We do not say it too loudly or attempt to scare anyone but are trying to be courteous and not scare someone by just racing past them with no advance warning.
Some riders seem to appreciate the notice while others seem offended.
We also make a comment how many riders are behind us if riding in a group or we may say something like "One rider on your left".
Do riders in the club have a preference or is there any recommended procedure for notifying slower riders as you pass on the left? Is it better to just pass someone or is it advisable to give notice that one or more riders are passing on the left?
I would be interested to hear if there is a consensus among club members. I will say from experience that very seldom do pace line groups or single riders make any comment when passing.
Thanks,
