Young runner Jamie Philpott broke a course record when he took part in the annual Royston Fun Run.
The 13-year-old, a pupil at Edwinstree School, ran the 3km event in a staggering 10 minutes and 36 seconds, the fastest time ever recorded in the event.
Race director Maurice Hill said: “It certainly was an impressive run.
“I can’t remember anyone ever completing the course in a faster time. It’s a huge achievement and he should be very proud of himself, as should all the young runners who took part.”
The event, which takes place every April, attracted nearly 150 young runners this year, despite the windy weather on race day.
Mr Hill, who is also chairman of The Royston Runners, which organises and marshals the event, said: “It’s always great to see so many families and young people coming along to take part in this fun annual event.”
Youngsters from across the region travelled to the town to take part in the popular run. Steeple Morden Primary School had a team of 30 11-year-olds taking part, and there were pupils from the Meridian School, Roysia Middle School, The Greneway School, Icknield Walk First School and Studlands Rise First School.
Runners also travelled from Cambridge’s Chrishall School, The Perse School and Heritage Day School to take part.
Second place was taken by Meridian School student Gus Rees, 14, who ran the route in 10 minutes, 47 seconds.
In first place for the girls was Ellie Laughlin, 13, of Greneway School, who ran in 14 minutes and 12 seconds, followed by fellow Greneway School pupil Charlotte Conn who crossed the finish line in 14 minutes and 23 seconds.
