Britton started the Antirm International, an IAAF Cross Country Permit meeting, as the clear favourite having defended her European title last month and won last time out in Edinburgh.
The 28-year-old's efforts 12 months ago, where she beat Britain's Gemma Steel in poor conditions, only added to the expectation that Britton would win, and she didn't disappoint.
Instead of Steel it was another Brit, Louise Damen, who pushed her close however Britton had too much at the end and opened up a significant gap to clock winning time of 18:17.
Britton's preparations for March's World Cross-Country Championships continue to go from strength to strength and she finished 12 seconds ahead of Damen who took the runners-up spot.
Damen was in turn 16 seconds ahead of third-placed Kenyan Magdalyne Masai while Linda Byrne was fourth before Eunice Kales in fifth, Freya Murray-Ross in sixth and Steph Twell in seventh.
Meanwhile in the men's race Uganda's Thomas Ayeko was an even clearer winner as he posted a time of 33:08 with Kenyan David Bett 37 seconds adrift in second.
Britain's Andy Vernon took third with a time just inside 34 minutes, 33:59, while teammate Frank Tickner was fourth 14 seconds further behind.
