most of the track is just dirt from the grass being trampled down, in smaller places I have patches of pea gravel, but just like in their feed runs and then a small section randomly on track
Your center looks amazing! I retired my horse to a place that uses the Paddock Paradise track system (but quite a bit smaller). Wish there were more places that did this. It's so good for the horses.
Very nice! Do you ever have one horse run another through the fence? We have a problem in the big pastures with this and I am not sure ours wouldn't be going through fences all the time.
The goal with the track is to not have any dead ends. That way a horse always has a way to get away from another. In the areas where they hang out together a lot, I make those parts of the track wider.
