Loction: out the back of the Motorplex somewhere - entry is usually from the LH side gate. Rather than the short circuit inside the Motorplex boundary, this will be a longer circuit outside the boundary.
Format: One hour racing - one hour service - one hour racing.
Timing: Buggies start at 0900hrs, 4x4s start at 1000hours (when the buggies come in for service). However...if this is a 20km circuit, the last vehicle could finish (say) 20 minutes after the hour, so the timings could easily end up a lot longer....who knows?
And if it starts on time, it will be the first time in history.
But it should be fun!
