A male motorcylist aged in his 60s will be airlifted to Canberra Hospital after a high-speed accident at the Wakefield Park Raceway near Goulburn.

NSW Ambulance paramedics responded to a call from the raceway in Tirrannavillve about 11am and the Snowy Hydro SouthCare Helicopter was sent to the racetrack about 11.20am.

A NSW Ambulance spokesman said the motorcyclist was unconscious when paramedics arrived but has since regained consciousness.

A Snowy Hydro SouthCare Helicopter spokeswoman said the man would be airlifted to the Canberra Hospital.

A Wakefield Park Raceway spokesman said the track was hosting a "recreational ride day", which was open to the public and restricted to motorcylists only.

He said close to 80 motorcylists were on the track at the time of the accident and that such incidents were common at public race days.

The helicopter was still at the raceway shortly before 12.30pm.
