The first round of this year's William Hill Greyhound Derby gets underway this week and following a bumper entry, we have thirty-six heats spread over Thursday, Friday and Saturday evenings.

Racing Post greyhound expert Jonathan Kay joins Mark Walton to look ahead to the action, previewing Thursday evening's heats on this podcast.

Jonathan also asseses the Outright Betting and at 12/1 the field, there's plenty of potential value on offer.

Enjoy.
