Really need to know how many competitors there will be before I actually announce the final set of rules.

But basically, it will work like this. In January, we'll choose our initial stable of around 10-12 horses. There will also be two further trading periods in the comp where we will add a couple more horses (before the Blue Diamond and before the Golden Slipper). Anyway, the person whose stable of horses has earned the highest amount of total prizemoney in the period from January 26 to April 14 will be the winner.
