This all makes me so sad. As many of you know, I grew up on the Trentham track... my father was Track Supervisor there from 1976 to 1987 and it was such a big part of my life during my teen years (11 to 22). He learnt his trade from the great Alf McCarthy and even though I'm biased, they were great days on the champagne turf.
The track is on an old riverbed, it's drainage has always been difficult due to rock bed not far beneath the surface. It has a natural cant from outside in, if the track is unyielding and there is additional moisture then it's natural the softer areas will always be on the inside. It's difficult, because of the lack of excellent drainage the surface has to be prepared for upcoming weather, well soaked, to prevent cutting out if later rain on a good surface, or a good surface of grass to keep some hold and cushion. The other issue that Trentham has is not enough racing now, so you get a lot of new growth, and it's not worn, it's lovely, green and shiny, and any moisture it gets slippery, so you have to have harsh brush and take the shine off, and/or allow some track gallops on it, so it's never an easy pathway when courses move from training bases to just race tracks because it adds another layer to track management.
Perhaps they need to consult some old heads until they work out a sustainable path forward 🙂
