Croydon Harriers began the summer campaign at the Wimbledon Young Athletes open meeting on Sunday.

Sprinters Charles Hagan and Marcia Sey with performances which ranked them in the top three of the UK U13s rankings.

Hagan’s storming 100m run of 12.30 seconds propelled him to top of the UK standings in his debut outdoor season.

Sey’s winning run in the girls’ 200m of 28.06secs is the fastest outdoor time this year in the UK for her age group.

Other sprinters who also shone included Chuks Ajeh (U15 boys 100m, second in 12.06secs), Kayla Bowley (U13 girls 100m, third in 13.79secs) and Tosin Salami (U15 girls 100m, third in 13.16secs).

In the middle-distance events, Stevie Lawrence bagged third in the Dave Clarke mile in five minutes 17 seconds, and Patrick Lucas was fifth in the male equivalent in 4:36.

Omar Harhara was the pick of middle distance runners finishing joint fourth in the U17 men's 1,500m in 4:26.

On the field, Emma Fossett laid down a solid opening marker in the U17 women's javelin topping the standings with a throw of 38.14m, eclipsing the English Schools standard in the process.

There were also wins for Anieshka Mido (U20 women’s shot, 8.73m) and Zoe Fossett (U20 women’s javelin, 27.49m).

In parkrun action, David Brown triumphed at Riddlesdown in 18:00, and there were runners-up spots for Alex Penfold (Roundshaw Downs, 17:46) and Glenn Barden (Pymmes, 19:29).
