In horse or dog racing, for a Pick 4 bet...?

Question

do you have to pick the winner of all 4 races BEFORE the 1st race of the pick 4 starts, or can you pick the winners one at a time, race by race after seeing the tote board?

Answer 1

bet em all at the start............................im not telling u not to but,,, i personally dont like animal racing.    cruelty to animals

Answer 2

You have to bet them before the first race is won. That is part of the challenge. So study the races ahead of time if you want to bet a PICK-4 or PICK-3.  Good luck!
