My horses are whatever I need them to be at the moment.
Most days they are trail mounts, but maybe I feel like working on some kind of pattern, or maybe we're going to do ground games, or maybe I got things that need hauled out of the woods (uhg fallen trees!), or I might need a quick ride down to a neighbor, and sometimes even lesson mounts.
They probably never work more than 8 hours a day on the longest rides, but this is all between whenever the weather warms up and right till it starts getting wet and soggy down here in the good ol south
During the "hard working" times of the year, I like the work one day, rest the next, routine with maybe the exception of riding both weekend days if the weather is lovely. It keeps them from burning out and plenty of relaxation and "horse" time. But once the freezing rains come in, they get turned out to pasture with a bale of hay for pretty much the rest of the year. During this period I do ground work exercises to keep me seen as their "alpha" and don't have such a headache when it's time to bring them back in work.
When it's cold outside though I still love to go outside and just hug and brush all over them at least once a day, it's a great joy to just be around such large and amazing creatures... specially the two I love quite a lot :3
