She may have run out of puff on the final night but it could not dampen the spirits of new world champion Lauren Boyle, who is excited about her future in swimming after a double medal haul at the world short course championships in Turkey this week.
Boyle finished eighth and last in the final of the 200m freestyle on the last day of the meet this morning, after breaking the New Zealand record in the heats earlier in the day.
The North Shore swimmer, coached by Mark Regan, clocked one minute 55.40, just over a second under the previous record set by backstroke star Melissa Ingram in 1:56.32 in 2008.
Boyle said that she had treated the morning heat like a final as her best chance of qualifying and had nothing left in the tank in the evening. She was 2s slower in the final.
American Allison Schmitt overcame her position in lane one to win gold, touching home in 1:53.59 ahead of Hungary's Katinka Hosszu and Melanie Costa Schmid of Spain.
Schmitt's gold added to the one she won as part of the United States women's 4x100m freestyle relay team, while Hosszu's silver takes her tally from Istanbul 2012 to five - two gold, two silver and a bronze.
With victory in the 800m freestyle and third place in the 400m freestyle, Boyle is buoyed by her performances in Turkey.
"I am really excited again. I am really happy with how things have gone over the last five days," Boyle said.
"I am still a fair way off world records so it's possible to improve more. I am happy with the improvements I have made.
''It is not going to be easy to improve from here but I am still very motivated and determined to improve and I am excited to keep swimming to see how good I can get."
Boyle believes that while the longer distances are her target, getting faster is also important.
"I am pretty competitive worldwide in the 800 and 400 but at the same time improving my 200 time will help my speed for the 400 and in turn the 800, too.
"I have developed my speed which was a big plus this week as I did not know I could go that well in the 800. But at the same time I've learned from the 400 where I did not do as well as I wanted that I need to make sure I can still back up after a big race."
In other swims Ingram was 15th fastest in 1:57.38, producing her best time of the year to complete a strong championship for the veteran North Shore swimmer.
Earlier, Howick Pakuranga's Corey Main was 17th fastest in heats of the men's 200m backstroke in 1:54.70, to be a fraction outside his best with the top eight through to the evening finals.
