Sebastian Coe wants to become president of track and field's governing body.
Coe tells the Times of London he will run for the top job of the International Association of Athletics Federations in 2015.
He says: "I'm ready. I know how to do this."
Coe is head of London's Olympic organizing committee and a two-time Olympic gold medalist in the 1,500 meters.
He is already an IAAF vice president. IAAF President Lamine Diack's term expires in three years.
Coe says "we have a great president in the post, so it would be when he stands down."
Coe's chief rival is expected to be Ukrainian pole vault great Sergei Bubka, who is also an IAAF vice president.
