Triathlon great Flora Duffy has won Bermuda's first Olympic gold medal with a commanding performance.
But Australia had another bad day, with no top-10 finishers in the men's or women's individual triathlons for the first time at an Olympics.
Duffy, a two-time world triathlon series champion enjoyed a perfect race on Tuesday at Tokyo's Odaiba Marine Park, finishing the 1.5km swim, 40km cycle and 10km race by herself in one hour 55 minutes 36 seconds.
It is Bermuda's second Olympic medal, following a bronze in boxing at the 1976 Montreal Games.
"I was Bermuda's first medal hope in many, many years and something I wanted to achieve for myself but also for my country. I was definitely overwhelmed," Duffy said.
The four-time Olympian and 2018 Commonwealth Games gold medallist finished a whopping one minute, 14 seconds clear of Great Britain's Georgie Taylor-Brown, who was left ruing a flat tyre late in the bike leg.
American Katie Zaferes was 13 seconds behind Taylor-Brown for the bronze.
Tuesday showed again that Australia's days as a powerhouse nation in triathlon at the Olympics are long gone.
Emma Jeffcoat, well-placed in the first chase group after the bike, faded on the run.
She finished 26th, some seven minutes and 21 seconds behind the winner, while Ashleigh Gentle and Jaz Hedgeland were lapped on the run and did not finish.
But the Australians are medal contenders for Saturday's mixed team relay, a new Olympic event.
Rain and wind delayed the start of the race by 15 minutes, meaning cooler conditions than the men's race on Monday, but also greasy conditions on the bike.
"It was absolutely crazy. I kind of feel a bit ripped off for all the heat work I did and for it to actually be kind of cool," Jeffcoat said.
There was no repeat of the false start fiasco in the men's race on Monday, with the photographers' boat well away from the swim pontoon.
British triathlete Jess Learmonth set a cracking pace and led a pack of seven out of the water that included all the medallists.
Jeffcoat led the chasers out of the water, 41 seconds in pursuit, but the front group built a solid lead.
Taylor-Brown had a disastrous flat-tyre late in the bike, leaving Duffy, Zaferes, German Laura Lindemann and Learmonth in front at the start of the run.
Racing in her fifth Olympics, Swiss great Nicola Spirig drove the pace at the front of the 10-rider chase pack and the gap to the lead was a manageable minute and one second behind at the bike-run transition.
But the 2012 Olympic champion and 2016 silver medallist could not mount a charge in the last leg of the race and Spirig finished sixth, more than two minutes adrift of the winner.
