Eilish McColgan broke Paula Radcliffe’s 21-year-old British women’s 10,000m record at the Sound Running Ten in California.
McColgan clocked 30min 00.86sec to win the event, shattering Radcliffe’s mark of 30:01.09 that she set when winning the European title in Munich in 2002.
Like Radcliffe, McColgan is set to shift her focus to the marathon distance and is planning to compete in London next month.
McColgan, who won the 10,000m title at the Commonwealth Games in Birmingham last year, now holds British records from 5,000m up to half-marathon distance.
