Claire Steels, an age group winner at the World Duathlon Championships in Australia in 2015, is flying again so far this year.
Last month she started her season by storming home first in the Grafham Water Duathlon and then she was a winner in the Dambuster Duathlon at Rutland Water.
The Bourne Town Harrier, who only took up the sport a couple of years ago, completed the course of a 6.25-mile run, 26-mile bike ride and then another three-mile run in a time of 2:12:16.
She was fastest female, and an age group winner as well, with 41st overall in a race that attracted nearly 400 entries.
It was also a qualifier for the World Duathlon Championships to be held in Aviles in Spain in early June.
With the first three in each age group qualifying, Steels comfortably made it on the plane to Spain.
Joining her will be three members of the Peterborough Triathlon Club who all won their age groups.
They were Paul Vernon, who was fourth overall, Jim Fell and George Prodrick.
Fell qualified to represent Great Britain at the World Championships for the third year in a row while Prodrick is making his international debut.
Robin Brookes, also PACTRAC, finished third in his age group and also qualified, but had to decline the invitation.
Steels went into the bike section with a slender lead but was convinced there was another girl ahead of her.
So she spent the whole of the 26-mile bike ride chasing a non-existent competitor.
She only realised that she was in first place at the second run turnaround and came home to win by more than three minutes.
Steels said: “I’m so happy with how the race went.
“Last year the Dambuster destroyed me – this year I got my own back and I even enjoyed the second run.
“I was very surprised but at the same time delighted with first female.”
