Nature Calls 15K and 5K Trail Runs

Prepare for an authentic trail running experience at the Nature Calls 15K and 5K Trail Runs, set for June 21, 2026, in the stunning natural landscape of Chattanooga, TN. Hosted by Wild Trails at the picturesque Lula Lake Land Trust, this event offers a unique, low-key, and no-frills approach to competitive trail running, with all proceeds benefiting the vital conservation efforts of the Lula Lake Land Trust.

Runners can choose between two distinct trail challenges. The 5K course is generally considered one of the easier trail runs in the area, perfect for those new to off-road racing or looking for a scenic, less demanding experience. However, the 15K course promises a significant test of skill and endurance. This challenging route includes the renowned High Adventure trail, featuring a memorable rope section and a demanding descent to the magnificent Lula Falls, offering breathtaking scenery alongside a true athletic endeavor.

Participants should be prepared for typical race day conditions, with historical weather showing highs around 90F and lows around 69F, accompanied by a 17% chance of precipitation. This cupless event emphasizes environmental stewardship, requiring all runners to bring their own hydration systems, as aid stations will offer water, Tailwind electrolyte drink, and various snacks, but few to no cups. Both races begin at 10:00 AM EST, and hikers are welcome on both courses provided they can maintain a 16-minute-per-mile pace.
