Is it open racing? if so you've got a chance, if not good luck

If its raining you'll soon see an advantage for the wide runners, the track sloaps towards the inside and the ground becomes sticky as the rain naturally converges on the inside, so dont wait for a pattern to emerge get on the wide leaders early!
The graded 6 bend races are absolute pony, i cant remember seeing one where at least 4-5 of the dogs have taken up the lead at one point in the race, very strange but all form goes out of the window, interest bets only in those!
good luck
