Question

How do you work out odds for each-way and win, double's and triple's in horse racing?

Answer 1

To calculate the unit returns for a win double add 1 to each price and multiply out e.g 9-4 and 15-8 becomes 3.25 x 2.875.  For a treble, if third horse is 6-4 multiply the above by 2.5. The above returns are for one unit stake i.e. £1 so if you have £2 on multiply by 2.

Same principle applies to a place double or treble. Divide win odds by appropriate fraction 1/4 or 1/5 then add one and multiply out.  Above example 2.25/4 plus one x 1.875/4 plus 1.

If you know how to operate a calculator, you cannot go wrong - do a simple example to prove it.
