Star sprinter Buffering is back in light work and is an odds-on favourite for a record breaking win before he even gets back to the racetrack.

Buffering missed the winter carnival with a leg injury and was spelled for two months before his recent return to Robert Heathcote's stable.

Heathcote is setting Buffering for another shot at the Group One Moir Stakes at Caulfield in October as an eight-year-old.

The trainer is also confident Buffering can be named Queensland's Horse of The Year for the fourth time, the first horse to do so since the introduction of the awards in 1971.

"People seem to forget Buffering was the only Queensland horse to win a Group One race this season. It was in the Moir Stakes when he beat Lankan Rupee and his other spring runs were very good," Heathcote said.

"He is coming along for another campaign."

Last year Buffering beat an all-star field of Horse of the Year contenders including Spirit of Boom, Temple of Boom, River Lad and Solzhenitsyn to be named Queensland's champion.

However, this year he has no such opposition with Queensland horses failing to fire at the autumn and winter carnivals.

The Liam Birchley-trained Hardline won the New Zealand Karaka Million and stablemate Blueberry Hill won the Group Two Champagne Classic.

Queensland's only other Group Two winner this year was Jetset Lad in the Brisbane Cup.

This year's Moir Stakes on October 2 has been reduced from 1200 to 1000 metres while the Group Two Schillaci eight days later is now 100 metres longer at 1100 metres.
