Red Cedar Trail Half Marathon

Prepare for an unforgettable trail running experience at the Red Cedar Trail Half Marathon, 40K, and 5K, set for May 30, 2026, in scenic Makanda, IL. Nestled within Southern Illinois's breathtaking Shawnee National Forest, this event kicks off from Pavilion 5 in Giant City State Park, offering a blend of challenging terrain and immersive natural beauty.

The course is a true trail runner's delight, predominantly featuring technical single-track trails with sections of runnable gravel roads, horse trails, fields, and minimal paved connectors. Expect significant elevation gains, with over 1,500 feet per half-marathon loop, and be ready for refreshing creek crossings, which may get your feet wet depending on recent rainfall. The Half Marathon is a single demanding loop of the 13.1-mile Red Cedar Trail, while the 40K challenges ultrarunners with two loops. A new 5K option for 2026 offers a taste of the Red Cedar Trail's charm. Typical race day conditions include highs around 83F and lows around 61F, with about a 15% chance of precipitation, making for potentially warm and humid trail adventures.

What truly sets the Red Cedar Trail races apart is their rugged charm and vibrant community atmosphere, often supported by dedicated Appalachian volunteers. Aid stations are strategically placed, with two well-stocked stations and two hydration stops per loop for the longer distances, and one hydration station for the 5K, though this is a cupless race, so runners should come prepared with their own hydration solutions. Finishers are celebrated with a swag bag, a medal, and a complimentary cold beer (or non-alcoholic alternative) at the air-conditioned Giant City Lodge, famous for its fried chicken—a perfect reward after conquering the streams, cliffs, and forests of this exceptional Midwestern trail event.
