Horse riders, how would you like me, a cyclist, to pass you on a horse? I know wide and slow, but if I'm coming from behind, should I call out/ring my bell as a warning or is that unhelpful?
For context, on the outskirts of Cambridge we have a busway, alongside which runs a footpath/cycleway/bridleway. It's mostly 4m wide, fairly straight and has a smooth tarmac surface. I sometimes come across horses being ridden on it; the surface means I'm almost silent as I travel, and sometimes I'm coming from behind. What's the best way to pass?
