One thing to point out tho - if coasting:
Please make sure the horse/pony rider has seen/noted you are there!
It can make for a nasty drag race situation when you get alongside (possibly hung over - or gossiping) rider with horse whose brain is in neutral.
You are suddenly spotted, horse takes off as you slightly accelerate past, jockey tumbles off.........
I always aim to leave a 'sideways' length of horse between me & the animal I am passing - room for manoevere for all
C
Roof - when you coming hunting???
