About this race
Join the Tough Ruck 26.2 Boston 2026 mission and be part of something greater. We ruck in honor of our Fallen Military & First Responders. Tough Ruck finishers earn the official 130th Boston Marathon Medallion and recognition from the Boston Athletic Association.
Tough Ruck 26.2 is a group of military, first responders and civilians whose sole purpose is to Ruck in honor and in memory of America's Fallen Military & First Responders, while raising critical funds to support military families and families of the Fallen in times of need. We will walk 26.2 miles with our Rucks and carry the names of our Fallen comrades with us.
On April 15, 2013, the Tough Ruck participants were at the finish line of the Boston Marathon and joined the first responders to help those that were injured by the horrific blasts. They truly exemplify the best of what our Nation is. Tough Ruck is the only Ruck march partnered with the Boston Marathon and finishers are awarded the official Boston Marathon Medals and receive recognition from the Boston Athletic Association. Military Friends Foundation (FEIN 37-1462599) is the official charity of Tough Ruck Nation.
