The Prairie Spirit Trail offers a scenic out-and-back course that starts in Ottawa, KS, and winds through charming towns, heading south to Iola for 100-mile runners and Garnett for those aiming for 50 miles. The path, mostly composed of crushed limestone with sections of asphalt in town, is flat and accessible, making it ideal for both newcomers and seasoned runners looking for a personal best. With aid stations located roughly every 5 to 6 miles, the course remains highly navigable for crews. This family-friendly event encourages supporters to cheer on participants while enjoying the area, but keep in mind that pacers are not allowed for the 50K distance, though they may join for the latter half of the 100 and 50-mile races.
