Bourne Academy pupil Kayleigh Adams was the first Under-20 woman to finish the Spalding Sprint Triathlon on Sunday last week.
The Canada-bound army cadet was also the fourth female overall in a strong field of athletes.
She completed the race in 64:30, doing the swim in 6:21, the cycle in 36:43, and run in 19:34.
Adams and her family also held a barbecue at the event on Sunday to help raise money to finance the trip in the summer.
In the men’s race former Deeping triathlete Mat Stephenson was denied a third successive win.
The event returned to the racing calendar in 2012, when former British international Stephenson blasted to victory – a feat he repeated last year.
But any hopes of a third successive win were thwarted by national triathlon champion Andy Tarry.
The Beeston ace, a successful runner with Nottinghamshire club Redhill Road Runners before turning to the triathlon, won by more than three-and-a-half minutes in 51:27. He was the quickest in all three disciplines, clocking 5:48 for the 400m swim, 29:05 on the 18.76k bike stage and 14:59 on the 4.6k run and – together with his transition times – that gave him a final time of 51:27.
Stephenson was second in 55:01 with a swim of 6:17, bike of 30:06 and a run of 17:00.
