Race Info
The Hawk Hundred is organized by the Lawrence Trail Hawks and offers 100-mile, 75-mile, 50-mile, and Marathon distances on a 25-mile loop through the rolling single-track trails of Clinton State Park in Lawrence, Kansas. Runners in the longer distances repeat the loop while marathoners add a 1.2-mile out-and-back on the Nature Center Trail at the start. The 75-mile option was not listed among the 2026 registration options (100M/50M/Marathon only). Source
