Running Fence Run - Celebrating Christo & Jeanne-Claude's "Running Fence" - a 24.5-mile fabric fence in Sonoma & Marin Counties installed in September 1976

Join us in a thrilling homage to history and human endurance at the "A 2,516-Year Echo: Marathon to Running Fence." Trace the steps of Pheidippides and embrace the spirit of Christo & Jeanne-Claude’s "Running Fence" in an epic event that marries the tale of an ancient Greek victory with a modern artistic symbol of freedom. This year, we commemorate the 50th anniversary of the "Running Fence" and the astonishing 2,516th anniversary of the Battle of Marathon.

Also, we honor the 25th anniversary of the 9/11 attacks with a memorial service to reflect on resilience and our collective journey. On September 12th, 2026, lace up for a marathon, a 5K, or a 10K race through the scenic Sonoma County, where every stride celebrates history, art, and the indomitable spirit of the marathon. Choose your challenge, be a part of this moving tribute, and support meaningful causes as you run. Let's make history together!
