Embark on a true test of grit and endurance at the Catoctin 50k Trail Run & Half Cat on June 20, 2026, in Frederick, MD. This renowned event, known for its challenging character since 1994, plunges runners into the rugged beauty of Cunningham Falls and Gambrill State Parks. The 50K course is a demanding out-and-back journey along the rocky and technical Catoctin Blue Trail, starting at the Manor Parking Area. Runners will conquer approximately 5,600 feet of elevation gain and loss, navigating a relentless "always uphill" mantra as they traverse from Bob's Hill through the Frederick Watershed to the High Knob turnaround. The Half Cat offers a challenging 25K experience, starting at High Knob and retracing the 50K's return leg to the Manor, specifically designed for ultra veterans or those seeking a shorter, yet still formidable, challenge.

The Catoctin course is almost entirely shaded by luscious tree foliage, providing some respite from the typical race day conditions, which often see highs around 82F and lows around 63F with a 17% chance of precipitation. Numerous stream crossings offer opportunities to cool down, though persistent attention to the light blue blazes is crucial, as the course is famously difficult to navigate for those not paying close attention. Fully stocked aid stations at Delauter Road and Hamburg Road, in addition to the start/finish area, provide essential hydration with water, soda, and Tailwind, along with a variety of snacks to fuel your journey. Prepare for a mentally and physically taxing experience on these demanding trails; the Catoctin 50k is an authentic ultra event where self-sufficiency and perseverance are paramount.
