Sophie Williams set a new personal best of 12.11 in winning the 100m sprint at the 2019 North Island Colgate Games.
The 14-year-old Wanganui Collegiate School student also qualified with the best time for the 200m final, which was raced late yesterday afternoon.
Williams and four other juniors from Athletics Whanganui Inc joined forces with the Palmerston North Athletic and Harrier Club to take on the North Island's best.
The Colgate Games have been running for over 50 years and take place in the North and South Island every year in January.
"Sophie just competed in her first secondary schools champs at the end of the year and got a silver," head of junior athletics at Athletics Wanganui Inc Jodie Brunger said.
