DEFENDER 5k and 2.2 mile Ruck 2026 — Saint Petersburg, FL

4TH ANNUAL SGT. ANTHONY MUHLSTADT DEFENDER RUCK DEADLINE FOR GUARANTEED EVENT SHIRT IS MAY 15th. AFTER MAY 15th, T-SHIRTS WILL BE BASED ON AVAILABILITY. THANK YOU Proceeds to benefit local organizations committed to battling military suicide Ruck. Remember. Defend. Anthony’s Defender Run/Ruck or Walk is more than a physical challenge—it is a mission of purpose, remembrance, and ACTION. We ruck to honor Sgt. Anthony Patrick Muhlstadt, USMC, and every service member who has silently carried the weight of stress, trauma, and isolation while serving our country. Anthony’s life, service, and loss remind us that strength does not mean suffering alone—and that suicide prevention begins with connection, education, and courage. This event exists because suicide is claiming the lives of our active-duty military and veterans at an alarming rate, and too often the warning signs are missed. Anthony’s Defender Ruck was created to bring those conversations out of the shadows and into the open—where real change happens. When you participate, you are doing more than showing up: You are standing in defense of life You are raising awareness for suicide prevention You are funding critical training and resources that equip people to recognize the signs, have hard conversations, and intervene when it matters most You are honoring the fallen and supporting the living Whether you ruck in person, participate virtually or sponsor, you become part of a community that refuses to stay silent and chooses to lead with action. We ruck to remember We ruck to protect those still serving. We ruck so others know they are never alone. Thank you for stepping up, shouldering the weight, and defending hope. This year we’ve added a couple fun new options: Create-a-Team (ruck, run, or walk together!)
