Four-time British Olympian Paula Radcliffe has secured the Six Star Medal upon completing the Boston Marathon.

Radcliffe, 51, finished Monday's race with a time of 2 hours 53 minutes 44 seconds, placing her 117th out of 12,447 women that took part.

The Six Star Medal is awarded to runners who complete all six of the world marathon majors: Tokyo, Boston, London, Berlin, Chicago and New York City.

Radcliffe retired from competitive running in 2015 and in March completed her first marathon in a decade when she ran in Tokyo.

The Briton held the women's marathon world record for 16 years from 2003 with a time of 2:15:25 before it was broken by Kenya's Brigid Kosgei in 2019.

Radcliffe is a three-time winner of both the London and New York City marathons, and won Chicago in 2002.

Her first international medal came in Boston in 1992, when she won gold in the junior race at the World Cross Country Championships.

On Monday, Sharon Lokedi won the Boston women's race in 2:17:22, with the Kenyan breaking the course record of 2:19:59 from 2014 by over two-and-a-half minutes.

The men's elite race was won by Kenya's John Korir with a time of 2:04:45.
