The Hughes family from Kirton produced a five-star display at the Lincolnshire Schools Championships at Boston on Saturday.
William, Charles and Lily picked up five gold medals between them and improved their personal bests on each occasion.
William recorded a junior boys 200m and long jump double in 24.0 and 5.38m respectively while twin brother Charlie edged victory in the shot by one centimetre with 11.33m.
Older sister Lily recorded a senior girls sprint double in 12.3 and 25.4 as Rachel Bell took second on both occasions.
The 100m saw both athletes recording the same time while the 200m was more clear-cut as Hughes won by two-tenths of a second.
The trio’s Nene Valley Harriers clubmate Ashley Sandall was also impressive as he again broke 50 seconds to win the inter boys 400m.
The Donington teenager, who won the English Under 17 indoor 400m title during the winter, was just a tenth of a second outside his personal best when winning by almost seven seconds in 49.1.
Lincolnshire Under 17 400m champion Bradley Spurdens opted to run the two-lap race and came home two-and-a-half seconds clear in a PB of 2.01.8, taking half-a-second off his previous best.
Alex Hampson predictably won the 1500m, coming home half-a-minute clear in 4.09.5, while the field events saw a high class shot competition where Nene Valley newcomer Robbie Shaw threw 14.29m to relegate Ben Stephens (13.97m) into second.
The pair are coached by shot putt legend Geoff Capes, who clearly knows how to get the best out of them as they both produced PBs.
Shaw has won county titles in three disciplines, taking the Under 17 discus and hammer titles at last month’s Lincolnshire Championships at Grantham and now adding the schools gold in the shot.
Another thrower in form was Ben McCormick, who retained the inter boys hammer title with a PB of 32.95m.
Jamie Horne, who has cleared 1.95m this year, retained the high jump in that age group with 1.80m.
In the junior boys age group, Tom Lavender – competing against boys a year older – flowed over the hurdles to win the junior boys 80m event in 13.4.
Emma Hornsby won the high jump and long jump with 1.57m and 5.54 respectively, just missing out on a new best in the former but adding three centimetres to her PB in the latter – an event where she had already got the English Schools qualifying mark.
Ellie Mae Stokes was also in excellent form as she took the triple jump and javelin. Her triple jump distance of 10.19m was the first time she has gone beyond ten metres while her javelin effort of 31.61m was also a PB.
Jasmine Allen took the junior girls long jump with 4.99m, adding nine centimetres to her PB and going agonisingly close to her first five-metre jump.
She was also third in a quality 200m race in a PB of 27.0.
Lauren Brown went beyond ten metres for the first time when winning the inter girls triple jump with 10.16m and she also took the 100m by a tenth of a second in a PB of 13.6. In the sane age group, Alice Gibbons won the shot with a PB of 8.62m.
Chloe Prentice was just one centimetre shy of the 10m English Schools qualifying mark when retaining the junior girls shot with a PB, with fellow Bourne Grammar pupil Chloe Ladley second with a new best of 8.28m.
Bourne Grammar School were the most represented school at the championships, making up a large proportion of the South Lincolnshire team.
A year 7 competition was included in the programme for the first time with Bourne producing both of the shot champions thanks to Sam Sacker and Jude Gilbert.
