WOW - Ciaran O'Lionaird Pre-Olympic threshold run
Irish 1500 meter Olympian Ciaran O'Lionaird has been playing catchup this summer after being plagued by an Achilles injury during the spring.

Look out for Ciaran in the first round of the 1500 meters on Friday, the first day of track and field competition at the Olympic Games.
