Janse van Vuuren sent the hammer sailing out to 63.82m*, smashing the previous mark of 61.06m which she had achieved at the League Meeting in Pretoria last month.
"The first time I broke the record I didn't really expect it, but this time I felt better prepared and I felt I could do it," said the 20-year-old Pukke athlete, who is coached by Basie Koen at the HTS/VUT Hammer Throw Academy.
