Radcliffe 'signs out' from road racing after Boston

Former world record holder Paula Radcliffe says her "body is done" with road racing.

The 51-year-old secured the Six Star Medal - which is awarded to runners who complete all six of the world marathon majors - by completing the Boston Marathon on Monday.

The mum-of-two, who retired in 2015, finished Boston with a time of 2 hours 53 minutes and 44 seconds.

Writing on Instagram after the race, Radcliffe says she injured her calf at the nine-mile mark and that the race was the perfect way to "sign out" from road racing.

"Wow, thank you Boston," wrote Radcliffe.

"My calf went at 9 miles and I couldn't go full out from then on, but on the plus side the foot is great and I got to savour and enjoy those Boston Marathon crowds.

"That's me signing out on the roads now! Lesson learned that my body is done with that."

The former Commonwealth Games gold medallist ended her post with a hashtag that read "end of the road".

Radcliffe completed her first marathon in a decade when she ran Tokyo earlier this year.

The Briton held the women's marathon world record for 16 years from 2003, with a time off 2:15:25.

She won the London and New York City marathons on three occasions during her career, as well as Chicago once.
