Frithville runner William Wright has won the Denman Cup at Heckington Show.
William - who is returning to competitive athletics following an illness and spell in hospital in April - lead from the start in the 1,500m race to win the under 15s section.
Thirteen-year-old William won the under 13s 800m race two years ago.
The Denman Cup for athletics was presented by the daughters of the late Jack Denman, Catherine and Zena.
The original 1948 cup - once won by Sebatian Coe - was lost, and this cup was first presented last year in memory of their late father.
Kirton runner Calypso Priestley won both the under 13s 800m and under 15s 1,500m races for girls.
Both William and Calypso are Nene Valley Harrier athletes.
