William Swain admitted he was ‘delighted’ to be crowned the British Schools Modern Biathlon champion on Sunday.
The Boston Grammar School pupil won the under 14 boys’ title after competing at the Queen Elizabeth Olympic Park.
“I was delighted when I found out I’d won,” said William, who turned 14 on Friday. “I finished 13th last year, so my aim was to finish in the top 10. I exceeded all my expectations.”
William finished the 1,600m run in 13th place before completing the 100m swim - in the pool which was used at London 2012 - in third.
After a nervy hour-long wait for the final standings to be released, William discovered he had finished in overall first place.
William, of Almond Walk, Boston, trains four times every week at Spalding’s South Lincs Competitive Swimming Club.
He admits that swimming is his preferred sport, even if he does enjoy athletics training at school, under the watchful eye of teacher Richard Anderson.
After claiming 13th spot in the final at Crystal Palace last year, William (pictured) booked his place in this year’s showpiece event after winning his heat in York.
He began the final ranked in 13th, but finished the event on top.
“It was amazing to compete in the Olympic Park, especially in the pool,” Will iam added.
