Australian Chloe Hosking was glad to have come through a "chaotic" sprint finish to edge out Britain's Alice Barnes on stage three of the Women's Tour in Royal Leamington Spa.
Poland's Katarzyna Niewiadoma did enough to retain her overall lead.
Cecilie Uttrup Ludwig [Cervelo-Bigla Pro] and Grace Elvin [Orica-Scott] led a breakaway group of five, which also included Amy Pieters, the Dutch Boels-Dolmans rider who had claimed victory on stage two in Stoke-on-Trent, and Martina Ritter [Drops], but were eventually chased down with five kilometres left.
There was, though, a crash as the peleton closed in, which saw Pieters caught up along with Marianne Vos [WM3], who had been in second place overall, and Dani King [Cylance Pro].
Hosking, however, got her positioning right heading into the last 100 metres of the narrow rising finish on the Parade, where she edged ahead of Barnes and Ellen van Dijk [Team Sunweb], with Giorgia Bronzini [Wiggle High5] in fourth place.
The 26-year-old from Victoria said: "This is a highlight race for most riders on the calendar, so I feel really privileged to come away with my first win and first podium here. It is a phenomenal event, I feel like I have entered an elite group.
"There was a group of five that got away and for me that was a bit worrying. It took a bit of effort to drag them in. Once we caught them everybody switched their mindset to a bunch sprint.
"It was a bit chaotic, which is strange because it was probably the least technical finish we have all week, but it was nice that the sprinters got a chance."
Niewiadoma, meanwhile, managed to stay clear of any trouble as the WM3 rider kept the overall lead in the green jersey general classifications, although her advantage dropped to one minute and 31 seconds as Van Dijk moved up to second.
