A. Hop off your pony, hand the reins to your daughter, and start running towards them while they approach you at speed waving your hands in the air and pretending to speak in tongues.
B. Hop off your pony, block the track with your horses and assume your best grasshopper stance, complete with sound effects.
C. Turn your ponies/horses back in the direction you came, and head of at a cracking pace giving you time to find the perfect hiding spot to leap from the bushes when they pass, hopefully giving them a collective coronary or at least soiled bike shorts.
D. Line each of your mounts up with a bike, yell charge, start cantering and proceed to play a game of chicken.
