Chloe Squires was unlucky to miss out on bronze but still recorded a personal best of 47.04 in the Cambridgeshire County Championships under-15 girls 300m final.
Nene Valley Harriers girls were only split by one other athlete with Kelsi Ellis winning after a strong first 200m and being followed in by Amber Park. Squires was third in her 300m heat and seventh in the 800m final.
Jasmine Allen won the under-15 100m heat and came third in the final. She claimed silver in the 200m.
Lucy Molyneaux was third in the under-13 100m heat, fifth in the 200m heat and third in the shot final.
Squires, Allen and Molyneaux live in south Lincolnshire but qualify for the championships as they were born in Cambridgeshire.
Nene Valley ended the day with 23 county champions and a further 38 medallists.
Highlight of the day came from under-17 ladies shot putt. Nene Valley Harriers took a clean sweep of medals as Tierney Augustine won gold thanks to a club record and championship best performance with her throw of 11.54m, just pipping Pricilla Dadziea and Lydia Church.
The under-17 ladies discus was also dominated by the club as the young ladies took four of the top five positions.
