The 2020 World Para Swimming European Open Championships got under way in Funchal, Madeira on Sunday, with Patrick Flanagan, Jonathan McGrath and Róisín Ní Ríaín all competing on day one for Ireland.
Flanagan was the first Irish athlete in the pool, the Longford man put in a strong performance, finishing with a time of one minute 28.93 seconds in the S6 100m backstroke morning heat.
Speaking after the race, he said: "It's always nice to get the first race out of the way, the race felt pretty good, time wasn’t great; but I was pretty happy how I swam it."
Flanagan will return to the pool on Monday, where he will compete in the S6 100m freestyle.
Ní Ríaín made her debut appearance for Team Ireland in a major competition in the S13 100m butterfly final, where she finished sixth in 1:11.25.
This was the first of seven races for the Limerick swimmer this week, who has secured several minimum qualification standard times recently for Tokyo 2020.
Ní Ríaín, who will be back in action in the SB13 100m breaststroke final on Monday, said: "It feels great getting out to race and coming to Europeans, it’s been a great experience."
Jonathan McGrath was disqualified from the S8 400m freestyle.
