That was what I was trying to point out earlier, with the reference to Hunt Club / Grand National meetings ( four days in all ) on the same track over a fortnight, years ago. The course coped ok mostly- but then it wasn't used until Cup time. Lead up races to that carnival took place at Oamaru, Ashburton, Geraldine, Rangiora, Motukarara, even Blenheim if my memory serves me correctly. Those fixtures worked well, stood the test of time, and the date structure, while not perfect, did seem to work ok. At least we did know what happened when, and could plan a preparation around that.
Not only are the turf tracks stuffed ( as discussed ad infinitum ) but dates have been altered over the years without thought to the knock on effect.
I remember locally, dates uptaken by Riccarton when smaller clubs lost them, so they weren't lost to the region. Admirable in sentiment, but adding to the pressure on a grass track without realising the effects going forward.
Now we have the AWT to potentially ease the pressure- but again, the structure and dates are all over the place without any seeming purpose, and no plan that anyone is aware of, to renovate the said turf surface.
