“I can’t thank them enough.”
Mr Graney, said he was “feeling absolutely fine”, “very confident”, and had “no symptoms” prior to going into cardiac arrest.
He said: “I don’t remember collapsing but my last recollection is overtaking my cycling partner halfway up Ditchling Beacon, towards the end of the ride just before Brighton”.
Mr Graney was airlifted to the Royal Sussex County Hospital in Brighton.
Nick Prince was one of the doctors who saved him.
He said: “It was a privilege to be there when David needed us, and certainly very fortunate timing.
