St Albans Athletics club members Chloe McCarthy and Emily Hack won medals at the South of England Athletics Championships at Crystal Palace.
McCarthy, who is currently ranked eighth, in the UK, won gold in the Under-17 women’s 300m.
Her personal best is 39.7, although this run was slower due to the windy conditions.
Hack, ranked 41st, finished in third place behind McCarthy.
The pair are both part of the 4x300m St Albans Under-17 women's relay team who currently hold the fastest time in the UK this year.
McCarthy, Hack and St Albans team-mates Emily Wood and Holly Brando won the 4 x 300m Under-17 women relay at Bedford on Saturday in a time of 2.50.4 beating their previous best by one second.
