JEREMY Corbyn is limbering up for office by going on 7km runs several times a week.
The Labour leader, 69, is also taking regular bike rides and works out in an outdoor gym in Finsbury
Park order to keep fit in case he becomes PM.
His spokesman confirmed the Labour leader is “very active, both on behalf of the party and in his own personal life.”
He added: “Preparations for Government are extensive and comprehensive.
“He cycles and runs and goes to the gym and his allotment.”
Mr Corbyn is often seen out and about in a grey tracksuit.
But questions have recently been raised about his health.
His aides last week admitted he is being treated for an eye condition at a specialist hospital.
