Dubliner Barry Murphy leads an 18-strong Irish team at the Celtic Tri Nations Meet this weekend.
The annual event will see top swimmers from Ireland, Scotland and Wales compete for the Celtic Tri Nations Championship title in Glasgow, with heats beginning on Friday.
It is a big weekend for 27-year-old Murphy who is fresh from swimming in the Irish Nationals at the end of April at the National Aquatic Centre.
It is also the last chance for the London Olympian to qualify for the World Championships in Barcelona in July, as he chases the qualification time of 1:00.86 for the Men's 100m Breaststroke in that competition.
Murphy, part of the Irish High Performance programme after his return from Ireland from college in the USA, took the gold medal in a season's best of 1:01.35 two weeks ago at the Nationals.
Sycerika McMahon and Fiona Doyle have qualified for the pool events in Barcelona while Limerick based Chris Byran will compete at open water.
