Hey there, I am almost done with my full out, Minecraft horse racing mini game. It is a full, built out track, which yo cannot ride off of, so it keeps you on the track. It includes redstone technology which sets you up with a horse, and the way you start the race is all redstone engineered. And When you are finished the race, you can reset it and play again. As an added bonus, there is a sumotori arena, which will include horses! Can't wait to finish it and let everyone play on it!
ADDED: Horse Pen! (customize you horse)
Cobwebs on the track.
