Double-Amputee Retired Marine Finishes 31 Marathons in 31 Days on National Mall

"Jones said his runs have been going really well and has seen improvement. "I've been getting a littler faster with my runs," he said in October. "I'm getting more in shape."  However, running such long distances does not come without challenges. "It's tough to get out of bed every morning and do the exact same thing," he said. Jones headed home to finish his mission. On Friday, he ran in Baltimore, and on Saturday, Jones ran at the National Mall and invited the public to join him for his 812th mile.
