the last run-in I had with a cyclist, few years ago, was Mrs B, myself and dog walking along a wide footpath, clearly marked as 'No cycling' when a cyclist, male, 18-20 ish coming towards us on a long straight section decided to cycle between us even though we were over to one side. When he exited the gap between us somehow his right wrist was broken. Even now, years later, I as a former Close Combat Instructor just can't work out how that happened, the Police concluded he must have fallen off his bike, Mrs B and I remember it well, the cyclist doesn't, possible concussion?
