Katie-George Dunlevy and Eve McCrystal claimed time trial gold at the UCI Paracycling World Championships for the third year on the bounce.
The Irish tandem pair crossed the line in 41:2.51 to beat New Zealand's Emma Foy and Hannah Van Kampen by 55.28 seconds over the 31.2km course in Emmen, the Netherlands.
"We had form coming into it from our previous results," said an elated Dunlevy.
"I believed that we could do it, and I really, really wanted this one. I know Eve did as well. It was really tough out there. It was a flat course and that suited us, but it was a long, hard TT. We fought all the way. I am absolutely delighted to win again."
McCrystal added: "I enjoyed it. I could see a few riders ahead of us so it was nice ot have a carrot to push on and win in the end."
Ronan Grimes was also in action, placing 4th in the MC4 category in a time of 41 minutes 11second, just 33 seconds off the bronze medal. The Galway native is a relative newcomer to cycling but has impressed coaches with his consistent development and transformation into a real medal contender.
Meanwhile Paralympics Ireland have confirmed Ailbhe Kelly is to retire from the sport. Her final race will be tomorrow in the relay at the World Championships in London.
Kelly raced a 5:32:96 in the women's 400m freestyle S8 to finish seventh in her heat at the Worlds on Thursday, a time that was just a second outside her personal best.
But she later revealed that she would be retiring from international paraswimming after taking part in the relay on Friday.
"I made this decision a while ago," she said. "I think it’s just the best thing for me personally. I still really love swimming and I always will and it’s been a massive part of my life for years now but I just had to come to this decision because there’s been a lot of changes, particularly within classification, and the way it’s affected me personally. It’s just really difficult to be competitive in S8 for me.
"Even in my heat just there, there's no one really around me, I'm not really racing anybody which makes it really hard."
