It used to be run on the big grass track of course and used to attract the country's best 2yos. The one I always remember was Fouroux, trained by Clem Scott, beating Melton Monarch sometime in the early 80s.
Some of the greats won it, notably Inky Lord, Young Quinn and Noodlum. The best filly I remember winning it was Hilarious Guest. The most interesting filly to win it was Ar Miss who went on to become the mother of the brilliant Armalight.
Sadly, I wouldn't be able to name a single winner over the last 30 or so years, but that is because I don't follow harness racing much these days. Inky Lord is probably the most recent winner I could name.
