Michael McKillop clinched his second gold medal of the London Paralympic Games by winning the T37 1500m final for Ireland.
The Glengormley athlete, who won over 800m on Saturday, streaked clear of the field at the halfway stage. McKillop was so far ahead of runner-up Brad Scott of Australia, he had time to wave to the crowd before the finish.
The 22-year-old's winning time of four minutes, 8.11 seconds was a record for the Paralympic Games. The emphatic victory sealed McKillop's status as the world's greatest Paralympic middle-distance runner.
McKillop, who has cerebral palsy, had a season's best coming into the race more than 20 seconds faster than the next quickest in the field and it proved as comprehensive on the track as it looked on paper.
Content to sit behind Scott early on, he passed him before stretching clear from way out, already acknowledging the applause of the crowd as he came off the final bend to win by more than six seconds.
