Riding around Epsom and into Surrey, passing horses - both racing and domestic - is a regular occurrence.
I cannot remember the last time I had a problem on the road (narrow bridleways are another issue). My approach is a single ping on my bell when a long way back. As I approach, But still some way back I say quietly "Good morning rider. Cyclist behind OK if I pass?" That way, the horse knows it is a human coming from behind, and the rider knows it is a considerate cyclist. Most often the rider waves me through, but sometimes might say they are turning off in, say, 50 yards and I wait behind. Occasionally, a rider has warned that the horse is particularly skittish and I make an even wider pass.
Approaching a horse head-on, I slow, make eye contact with the rider, and pull in tight to the left.
