A new all-weather synthetic training track is to be built at Mornington Racecourse, replacing a sand training track.

The $2.75 million project, expected to be completed by next month, will be jointly funded by the state government, the Victorian Racing Industry Fund, Racing Victoria and the Melbourne Racing Club.

The existing track base and drainage will support the new synthetic track which will be the same dimensions as the old sand track - 1730 metres in length and eight metres wide.

The current sand training track is 12 years old and is no longer suitable for training RV said.

"This new, all-weather synthetic track at Mornington will ensure that trainers have access to top-quality facilities at one of Victoria's busiest racing and training centres," Victorian racing minister Martin Pakula said.
