Ninja 5K, 10K, & 13.1 at Fort Smith

Ben Geren Regional Park serves as the start and finish. A practical note for runners: "Use the parking lot across from the playground." The Ninja 5K, 10K, & 13.1 at Fort Smith follows a standard US Road Running format. Packet pickup is located near the start, and all registration is handled through RunSignup, with "No on-site registration." The course is an out-and-back design, meaning you will cover the same section of the course multiple times. Shorter races loop through a shorter route, while the 13.1-mile option repeats its out-and-back segment six times. This format suits runners who prefer a rhythmic pace, enjoy tracking splits, and want to know precisely what to expect. Finisher medals, awards, series points, and a best costume contest are included, adding a distinct, albeit small, race-series tradition.
