I guess it will have to be a bet of which horse finishes ahead of the other. Showing Up is likely to be 4-1 or better and EC 2-1 or better so it is pointless to bet only if one wins, which I am sure Showing Up will do. But I won't take even money when I can get 4-1 or better.

So, the bet can be which horse finishes ahead of the other. Correct?
