On the first of the four weekends comprising the Southern Youth Development League calendar, Eden Davis, Sophie Dowson and Anna Barnett each secured under-17 'A' event victories.
Herts Phoenix sprinter Davis won both the 100m and 200m races at Ashford, in times of 10.95 and 22.44 respectively. He was only deprived of an official PB in the longer event by the marginally high wind reading of 2.2 m/s.
Harrow AC pole vaulter Dowson cleared 3.20m for victory at her home track, while Anna Barnett, of Blackheath & Bromley, tossed the discus 29.63m to win at Stevenage.
Jessica Hurley placed second in the 300m at Stevenage in 42.29, while Rachel Ayrton won the 'B' 800m at Harrow in 2:36.6.
Alana Edwards, 15, recorded 50.8 to win the 300m hurdles at the Wigan Harriers Spring Open Meeting, while her sister Ellie, 18, took the 200m event in 27.2.
