Adam Peaty: Olympic champion wins 100m breaststroke at Northern Ireland meet
Olympic and world champion Adam Peaty earned a dominant 100m breaststroke victory on day two at the McCullagh International meet in Northern Ireland.
Peaty clocked 58.78 which was 1.90 seconds outside his world record mark.
The Englishman's Loughborough club-mate and world silver medallist James Wilby took second in 59.91 with Scotland's Ross Murdoch third in 1:00.54.
Peaty, 25, is also competing in the 50m and 200m breaststroke events at the Bangor meet.
The event is following the same format as this year's Olympics with heats taking place in the evening followed by morning finals.
Peaty admitted that the format change will take some getting used to but he was happy with his Friday morning swim.
"It was very good. It's always harder coming in racing in the morning especially when you are not used to it," Peaty told BBC Sport Northern Ireland.
"This is the start of my prep now. It's only a few months to the Olympics and we're just looking at how we can get those extra gains."

Englishmen Max Litchfield and Edward Mildred filled the top two spots in the 200m butterfly with times of 1:59.53 and 1:59.97, with Ireland's Brendan Hyland third in 2:00.04.
