race with a clear favorite; safe-bet race
Used in horse racing and similar contexts for a race where one entrant is overwhelmingly expected to win, making it a low-risk bet. Often carries a nuance of being a 'banker' bet.
Today's main race is a banker race, so the payout will probably be low.
Horse racing beginners should first get used to it with safe-bet races.
Compound of 銀行 (bank) and レース (race), from the idea that betting on the clear favorite is as safe as putting money in a bank.
