If you're looking for races with small fields, then Exeter in the UK, is the place to be! Their race card overnight, comprised 2 x 7 horse, 2 x 4 horse and 3 x 2 horse races. And if you think there's no money for these races, forget it, as I think the smallest Betfair pool was 360,000 pound and over a million for one of the 2 horse races where you had a 1.05 fave and 18 2nd fave. Fortunately for some, the 1st fave got up (it was a Hurdle race, so anything can happen)
