Ireland's Jason Smyth beat his own World Para-athletics European Championships record to comfortably secure T13 200m gold on Tuesday.
The county Londonderry man, 31, clocked 21.44 as he remained unbeaten in a Paralympic career which began in 2005.
It is also a season's best for Smyth, who has won 17 international titles including five Paralympic gold medals.
Smyth's Irish team-mates Greta Streimikyte and Orla Barry also won gold medals on Tuesday.
Lithuanian-born Streimikyte, who moved to Ireland in her teens, won the T13 1500m title with Rio Paralympics silver medallist Barry triumphing in the discus after producing the six longest throws of the competition.
Barry's best throw of 28.76m was over eight metres further than Martina Willing's silver-medal winning distance.
Another Irish competitor Paul Keogan narrowly missed out on a T37 400m medal after finishing in fourth spot.
Smyth's time left him 0.43 seconds ahead of Poland's Mateusz Mateusz with Switzerland's Philipp Handler (23.45) awarded the bronze after the disqualification of Romania's Octavian Vasile Tucaliuc.
Smyth clocked his personal best of 21.05 when memorably setting his T13 world record at London 2012.
Earlier this summer, Smyth told BBC Sport NI that he believed he and his fellow Northern Ireland paralympic star Michael McKillop deserved greater recognition.
"I've been in Paralympics since 2005 and never actually been beaten. I don't know how many other people that fall under that category," said Smyth.
"If it was boxing, football or rugby and someone had gone 12 years unbeaten we wouldn't hear the end of it."
Smyth warmed up for the championships by setting a 100m season's best of 10.53 in London last week and he will be expected to complete the T13 sprint double on Thursday evening.
