Looking for horse to exercise

Hello! I am looking for an energetic horse to exercise a day or two a week. I own my own boy but unfortunately he is getting quite old and we are unable to go out on the long rides we used to do together. I have worked with and put miles on lots of different horses, from an 11hh green broke pony to helping restart my friend's OTTB. I have shown up to 3’ and schooled 3’3 at home. I am not looking to show, just hit trails and have fun a day or two a week. Not looking for a kick ride. More go than whoa. An Arabian would be preferred, but really any forward going horse is fine. No preference between mare or gelding, either is good. I am very responsible and have references upon request. Please send me an email if you are at all interested. Would possibly consider an off property lease.
