The Little Tree Project 2,500-Mile Challenge, by F3 Mobile 2026

The Little Tree Project 2,500-Mile Challenge is a virtual activity challenge based in Mobile, Alabama. The single shared goal is to log 2,500 miles collectively within one week during October. This is the second annual event organized by F3 Mobile. Participants can log miles from running, walking, biking, rucking, swimming, or other activities, tracking their progress wherever they are without a set race course. The challenge raises awareness about human trafficking and supports The Little Tree Project, an Alabama 501(c)(3) nonprofit assisting survivors in the Mobile community with care, recovery, and restoration. Individuals can participate alone or form teams. This event links F3 Mobile to a broader F3 initiative that started with men in St. Louis who expanded a virtual 5K into a week-long mileage and fundraising effort. F3 is a national network of free, peer-led men’s workouts, originating in Charlotte and now operating in all 50 states with over 4,500 weekly scheduled workouts.
