We got a run of post n rail, but stock with rail would be just as good, as a race, baz has made guillotine gate for end with long rope so we can use it from about fifteen foot back, then just a run of hurdles for sweeping behind them, double tied with twine, so you know they may pop but the twine does its job. Race fits eight to ten at a time, lovely! Or you could use some sheetting?
