A retired double-amputee marine sergeant will embark on a challenge to run 31 marathons in 31 days.
Rob Jones, who has previously ridden 5,200 miles across America, will begin his ambitious feat on Thursday in London before a planned finish in Washington, DC on Veterans Day, November 11.
The former bronze medallist at the 2012 London Paralympic Games in rowing hopes to have the support of fellow runners with him on his journey with the goal of raising awareness and funds for wounded veteran charities.
"I am just going to get up in the morning and just start running. I am going to remember the reason that I started running and support my brother veterans," Jones told Sky Sports News.
"Doing that is a lot more important than being bored or uncomfortable wherever I am going to be. That is what is going to keep me going."
Jones, who was wounded during deployment in Afghanistan in 2010, had both his legs amputated on after stepping on a landmine has also revealed he hopes to compete in the Invictus Games in the future and has sent a warning to fellow competitors should he feature in next year's edition.
He added: "Ever since I heard about it I have wanted to do it but it is just the timing for me. Next year I won't have anything to interfere so everybody who was there look out for me next year."
