An Irish Paralympian set the first adult world record in the new London 2012 Olympic Stadium on Tuesday in the 1,500m race.
Michael McKillop (22) hit a new record of 3:49.53, taking 15 seconds off his best time at the Visa London Disability Athletics Challenge on Tuesday afternoon.
"It's nice to be here and breaking a world record. I'm happy to be the first male to do it in the stadium," the Antrim athlete told reporters.
"It was incredible and enjoyable and an experience I wanted to get out of my system. It's one of those things - you want to walk into a stadium for the Paralympic final without worrying or thinking 'Oh my God, the stadium is huge' or 'the track is bigger'," he said.
"It's only a 400m track with lots of seats around it basically, so it's similar to where I train which is also a 400m track. I've just got to get used to it."
The Irishman is now tipped as a favorite for the approaching Paralympic Games' 800m and 1,500m events. The 22-year-old won T37 gold at 800m in the Beijing Paralympics four years ago.
"Whenever I step on the track, whoever I'm racing I always want to beat them and today I knew I was capable of running 3:59," a proud Michael added.
According to Paralympics.ie, McKillop is coached by his father Paddy, and will be targeting double Paralympic gold in London.
