About a 100 years ago I rode a few at Northcote. I rode the first one held at Vodophone but was sick, went terrible and ended up at hospital that night on the drip, so the memory is a bit hazy
Im just a spectator now. Format is the same as for the Austral, or pretty much any wheelrace. They have heats, first couple of placings from each heat go into the final. The rest of the racing program is generally a scratch race for each grade, with the Aces getting a few more rides.
