A US Marine veteran who lost both his legs in Afghanistan has successfully completed 31 marathons in 31 days.

Rob Jones needed double above the knee amputations after stepping on a landmine during a push into Taliban territory in 2010.

He was honorably discharged from the Marine Corps in 2011 and the 32-year-old has since dedicated his life to raising awareness and funds for wounded veteran charities.

The veteran finished his ‘month of marathons’ in Washington at the weekend having run 812 miles at events in 31 different major cities.

After being fitted with prosthetics Mr Jones said he had to “work hard to learn how to walk with two bionic knees”.
