Thankfully, that is where online odds calculators come into their own. For example, are you planning to keep it simple with a single bet on one race? Or, alternatively, are you looking to take a chance on a larger gamble with an accumulator? While putting money on a horse winning a race may sound like a relatively straightforward matter, there is a wide range of bets available. Whether you are new to the world of betting or somewhat of an old hand when it comes to having a flutter every now and again, you will undoubtedly be aware of the sheer range of options at bookmakers like Betfair and Paddy Power when it comes to having a bet.
