I ride with my gf and her horse. Obviously the horse will leaving me for dead on the uphills, and she won’t be able to keep up downhill. But its fine as you aren’t joined at the hip…right?!
If the horse is nervous around bikes, then going along on the bike is even more sensible as they will become accustomed to the bike.
My gf used to ride a friends horse and he used to try and race me on the bike, and used to get upset if I went a different way. The current horse isn’t as playful. During a temper tantrum last weekend she managed to stand on my back wheel whilst spinning around on the spot, no damage done luckily and more importantly the horse lost the ‘I want to gallop’ argument and was made to walk sensibly for a bit 🙂
The only stipulation when I ride with a horse is that we don’t do any uphills involving ploughed fields 🙂
