Doesn't everyone want to race their horses on a Good rates track?
Honestly I think the NZTR protocols are a big part of the problem. If the forecast rain had have happened they would have run on a S5 or even a G4 but with the horses getting through the surface.
That's just my opinion based on observation. I literally followed the forecast and records hourly for the 24 hours prior to start time. There are NZTA intersection cameras on the Wairere Rd/Te Rapa road intersection.
Barely any of the 15mm+ happened and then around 11am it hosed down for a brief period.
Otherwise it would have been a perfect surface. The fact is the soil is spent. A bit like most of the buildings there.
