The annual competition, which takes place at Loughborough University’s Paula Radcliffe Stadium, saw the 22-year-old from Nottingham clock a time of 12.43s - in only her third 100m race of the season - to break her own record in front of a jubilant crowd.
Speaking after her victory, Sophie said:
“I’m so surprised and I can’t believe that just happened. I didn’t expect that. This is only my third 100m race and [that] shows I’m in good form.”
