Lauren Boyle has become the first New Zealand swimmer to take two medals from a single world short course championship.
The 25-year-old from Whenuapai added bronze from the 400m freestyle this morning (NZT) in Istanbul, Turkey, adding to yesterday's 800m gold.
Boyle was close to making it a second gold, leading for the majority of the 400m freestyle final but in the final 25m was chased down by Melanie Costa Schmid of Spain and American champion Chloe Sutton.
Boyle was just 6/100ths of a second from a second title.
Having only had a few hours sleep since taking 800m gold yesterday morning (NZT), Boyle acknowledged the best 24-hour window of her career.
"I'm really excited to have won medals here, it's a big breakthrough for me," Boyle said.
"The last 100 m wasn't really good tonight but I am really stoked to be on the podium again. It's a good result but there are always things to work on.
"It was a pretty hard back-up just because the 800m is quite a long race so it takes a bit out of you. To have the heat this morning for the 400m was quite a short turnaround.
"It was a good day and a half of solid racing."
The New Zealander now has a rest day before her final event of the regatta, the 200m freestyle.
"Tomorrow I need to carry on flushing my body out and rest a bit. I feel like it's a bit sore and tired from the two longer races today and yesterday," she said.
"I guess for the 200m my final will kind of be the heat because it's not one of my strong events. I'll have to work pretty hard to get a second swim."
Meanwhile, promising men's freestyle prospect Matt Stanley fell just short of the 400m podium, finishing fourth.
Stanley, 20, swam faster with each outing in Istanbul, lowering his entry time of 3:42.17 to 3:41.59 in the heats and he cut a further half a second off in the final to 3:41.01.
However, the London Olympian believed a medal was in his grasp.
"Fourth is like first loser. I wish I had backed myself a little more and I could have come away with a medal may be," Stanley said.
"I didn't have the easy speed I needed through the first part of the race and I wasted a bit of energy and went out a little bit slow which was a shame."
His best is 3:40.74 when he win the World Cup in Beijing recently and he now begins to circle on another Danyon Loader national record of 3:40.46 set in 1995 in UK which broke the world record at the time.
