“This meant everything to me. I wasn’t expecting to come away with a gold medal. I was hoping to medal, but wasn’t thinking of the gold. Hopefully everyone on our team can feed on that energy and a few more medals will come.”

Nicolo Martinenghi (Italy)

“I don’t consider myself the top favourite here. I’m just one of the swimmers who clocked the best time today but the other day another guy might have won this event just like I did now. It’s a big family where we are all equal. Of course, I’m happy with my result, it was close to my best, but it was a hard day with three 100m breaststroke swims (two in the mixed medley relay). It was a long season with a lot of races, junior Europeans, the Worlds in Budapest and now this one here. I’m satisfied what I have achieved so far. I don’t know what the future holds for me, I only know that I want to work hard or even harder.”

Ruck's teammate Jade Hannah was third to arrive, earning the bronze medal for Canada.

Regan Smith (USA)

“Setting the world junior record was insane. Doing it at world championships in the 200 back in semis was crazy.  After a kind of disappointing final, I really wanted to come back strong at this meet and I’ve been thrilled with how it’s gone so far. I’m just really happy.”

On the mixed medley relay

“My teammates with me on the relay were so great and so supportive and they made me feel so confident and so excited and I felt so pumped to swim for Team USA. It’s such an honour and I have so much fun doing it and I love it so much.”

Johanes Hintze (GER)

“It was the girls’ idea to paint the national colours to our faces and I told them why not, even if I’m swimming a final I wanted to be part of the fun. And of course I’m proud of my country! The swim felt great, you know, I had a serious injury earlier this year and I wasn’t sure if my shoulder would be OK for this championships. So I’m really happy as I did a great job here.”

I am very satisfied with my time and I wish to thank my coach, my family and a special thanks to Bill Sweetenham. Thanks also to my team members for their support during the race!  I realized I could win after the 300m mark, but it was a very tough competition. Although it was difficult I enjoyed the race very much."

The Russian team was third to the wall to secure their place on the podium.

Penny Oleksiak (CAN)

“I just wanted to be here for the relays and to be with three girls I train with every day. Just having the team together at meets and training it’s good for the long run. [After becoming Olympic champion in Rio] Everything is pretty much the same, having my parents and a good supporting team definitely help me to stay grounded and to stay with my normal life.”
