As promised I have found something. Want a $200/1 winner??? well even a decent place price will do. It is Ascot Race 2 no 9 Spirit Of Gerry. Don’t ask why but I have done my research.
A more likely result is Sandown Race 3 with two runners No 6 Ultimate Kiss $3.20 Fav and 5 Mere Fancy $4.80. Check your money back options and have one at one agency and the other at another if available. So it would be $32 on the 6 to return $100 and $21 on the 5 with potential to get credits back for both or for one and a win or of course zero zero but to my mind it is worth a punt. Of course you could go $3 and $2 if you are on a small budget.
