However your problem is simply of odds, you cannot bet a set amount regardless of prices!

If you left out the $20 bet it would possibly work most of the times depending on odds again, but in this case you have to write a formula that automatically adjust the bets on the other runners to make sure that you either break even or win, whichever event occurs.
That shouldn't be too hard except I don't know if your bot could handle it?

Good luck with it
