Cheltenham Contest?

[Pedigree Ann]

I entered the Racing Post contest for 5 quid, in which my first day horses were:
Supreme Novice's Hurdle - Numide
Arkle Chase - Tidal Bay
Champion Hurdle - Osana

You get bonus points based on odds, so picking against the favorites makes some sense. One hopes Sizing Europe, for instance, is coming down with a cold and runs below par, opening the door for a second or third choice, that sort of thing.
