Land speed record attempt: Maximuscle founder Zef Eisenberg killed
Ultra-speed motorbike racer and businessman Zef Eisenberg was killed while attempting to break the British land speed record at Elvington Airfield, North Yorkshire Police have confirmed.
Mr Eisenberg, 47, was the founder of sports nutrition brand Maximuscle.
Mr Eisenberg ran the Madmax Race Team, which attempts speed records with motorbikes and cars.


He held speed several records, including the record for the "flying mile" at Pendine Sands in Wales.
He died at the airfield near York yesterday (Thursday).
North Yorkshire Police said in a statement: "Shortly after 4.30pm on 1 October 2020 we were called to a serious vehicle incident at Elvington Airfield near York.
"The incident occurred during a British Land Speed record attempt and the driver, 47 year-old Zef Eisenberg tragically died at the scene.

The privately-owned venue, which is an active airfield, is also a facility for driving, driver training, filming and other testing purposes for professional organisations.
