Stimpson, second overall in the ITU World Triathlon Series following the PruHealth World Triathlon Grand Final in London, produced a commanding performance to beat Italy's Alice Betto and Rachel Klamer from the Netherlands.
The 24-year-old found herself part of an early break away during the swim alongside fellow Brits Lucy Hall and Natalie Milne.
And their hard work on the hilly bike route ensured Stimpson was in the best position possible to secure victory as she began the run – winning in a time of 2:02:39.
"It's brilliant to finish my ITU year with the win and having Lucy (Hall) and Natalie (Milne) there on the bike ensured it was a hard working group," said Stimpson.
"I just ran hard to finish and I'm chuffed with the win."
There was also success for another Britain in the men's race as world junior bronze medallist Grant Sheldon announced himself on the senior stage by finishing third. The 19-year-old finished behind 2004 Olympic medallist Sven Riederer of Switzerland and Vincente Hernandez of Spain and even had the fastest 10km run split of the whole field.
