OMG. I should invent an app that connects like-minded trail riders (like a dating site). " I enjoy long walks on the beach at sunset," vs. “I like to run 10 miles on the beach every morning;” “I like to take things slow” vs. “I believe in living life at high speed;” “I like to offer a sugar cube or two every day” vs. “I have not allowed my horse to consume anything containing more than 8% sugar in exactly 1134 days,” etc.
Then, there would be the horses’ version: “I’m a hairy chunk o’ muscle and I sweat like a pig!” vs. “My hooves do not actually touch the ground and I do not perspire for the first 35 miles.” “Unless there is mash coating your face up past your noseband, you ain’t enjoying your snack” vs. “Is that organic? Is it too warm? Is it too cold? Is it too wet? Is it too dry?” Or, “I don’t need no shoes!” vs. “Are the gaiters on my trail boots adequate to protect me from the mud?” And, “Heck, I love me a crupper! Takes care of the itchies back there!” vs. “Certainly not! Away from there, you cad!”
But to answer the OP’s question, finding well-matched trail partners can be an all-but-insurmountable challenge. But worth it when you find Mr./Ms. Right.
