Good idea. It would also be nice if people visiting the house could watch the race as they can watch the pvp circle. I once saw an epic castle whose owner fenced in the moat except for one entry point. He floated dirt and sand piles over the moat to make hills to run over and placed plants in the water for a slalom course. The whole moat had been turned into an obstacle race for wizards, either mounted or on foot. Anyone not racing could watch the race. It was a lot of fun. The only tricky thing is that due to lag in computers, it was hard to tell who won.
