Horse Racing Picks

In the race horses or dogs, a Pick 4 wager ...?

you must choose the winner of 4 races before the 1st race starts the truck 4, or you can choose the winners at a time, race after race to see the bag on board?

You must wager before the first race is won. This is part of the challenge. Thus the career of studying ahead of time if you want to bet a pick-4 and Pick-3. Good luck!
