It's as easy as adding an eligible selection to your bet slip and ensuring the button is enabled.
This is indicated by the bet return button being on and highlighted in blue. For all advertised races we will automatically enable the bet return to your selection when you add it to the bet slip.
View and select from your available bet returns and then place your bet (you will only use the bet return once you confirm your bet). If you don't want to use it for that selection, you can tap the bet return button to remove.
