And there's no guarantee the first bet hits. You're only getting better odds on him if the first bet hits. I often see bettors use parlays of race winners across multiple races to get 'better odds' in the second race on a driver they think is likely to win.įirst off, you're not getting better odds on the second driver. DON'T bet the parlay if you wouldn't bet each leg individually.Ĭalculations aside, it's not wise to bet a parlay if you wouldn't make each leg of the bet individually, assuming the bets aren't correlated. If a book is offering less than this number, they are holding more than they already do on each of the individual bets. So if a book is offering fair odds, we'd expect them to pay this parlay out at +3500.
Each bet that's offered at 5-to-1 odds needs to hit one in six times to break even. We can see, in this situation, the parlay in this example should pay out $3500 and return our $100 bet. The Action Network parlay calculator is a great tool to help you run the numbers. What are the fair odds of the full parlay in this situation? Let's say you are parlaying two props whose odds are offered individually at +500 apiece.
