Paula Radcliffe, the four-time British Olympian, has achieved a significant feat. At the age of 51, she completed the Boston Marathon on Monday with a time of 2 hours 53 minutes 44 seconds, placing 117th among 12,447 women. The Six Star Medal is awarded to runners who finish all six of the world marathon majors: Tokyo, Boston, London, Berlin, Chicago, and New York City. Radcliffe retired from competitive running in 2015 and ran in Tokyo in March after a decade. She held the women's marathon world record for 16 years and is a multiple winner of major marathons. On Monday, Sharon Lokedi won the Boston women's race, and John Korir won the men's elite race.
