Rock the Run 5k and 1Mile/Walk Fun Run

Billings, MT

Kick off a crisp September morning at Pompey’s Pillar with the 2026 Rock the Run 5K and our newly added 1‑Mile Fun Run/Walk! The 5K is officially RRCA‑qualified, making it a great choice for competitive runners and community athletes alike. The 1‑mile option offers a relaxed, family‑friendly way to join the fun—perfect for walkers, first‑timers, and anyone who wants to support the Pillar at their own pace. Every registration helps preserve and promote the history and programs of Pompey’s Pillar National Monument. Lace up, enjoy the scenery, and be part of a meaningful community tradition.
