Riding in a group can take some practice to get right and safe but it is great when it works.
We encounter lots of horses on the quieter country lanes we use for our club rides.
Our policy is to slow right down, talk to the horse riders, and to pass on the other side of the road. Sometimes horses can be startled by the sudden noise of a loud freewheel, so always just slow pedal.
Remember the horses may already be twitchy – you’re probably not the first to pass them.
