The rundown
The Last One Standing is a backyard ultra event in York, PA on Saturday, May 1, 2027. The field welcomes both professional and amateur athletes. Registration is open. Details are sourced from runningintheusa.com, so confirm timing and entry information with the official organizer before race day.
Course profile
The Last One Standing follows the standard backyard ultra format, challenging competitors to complete an exact 4.167-mile loop every hour on the hour until only one runner remains. Set against the rolling terrain of York County, Pennsylvania, the route typically incorporates the region's characteristic mixture of packed dirt trails, crushed stone greenways, and grassy park paths. While backyard courses prioritize runnable topography to allow consistent pacing, York's Piedmont topography naturally introduces gentle, undulating grades rather than extreme vertical ascents, requiring you to carefully modulate effort to prevent premature fatigue over countless hours.
Your primary adversary on this course is not a single punishing climb, but rather the compounding toll of micro-elevation and the strict 60-minute time cap per yard. Running surface conditions often alternate between firm, predictable footpaths and exposed tree roots or uneven turf that demand focus as visual fatigue mounts. Because no pacing or aid is allowed out on the loop, you must carry essential hydration and fuel during each leg, returning to the corral with sufficient time to manage nutrition, foot care, and brief rest before the starting bell rings again.
Plan your trip
York is conveniently accessible by vehicle via Interstate 83, which runs directly north-south through the city connecting to Harrisburg and Baltimore, and U.S. Route 30 for east-west regional transit. For air travel, Harrisburg International Airport (MDT) is the closest option, located roughly 30 miles to the north, while Baltimore/Washington International Thurgood Marshall Airport (BWI) lies about an hour south and offers broader non-stop domestic routes. Booking lodging along the I-83 corridor or near central York provides straightforward access to local race venues, grocery stores, and pharmacy supplies.
Early May in south-central Pennsylvania generally brings daytime highs in the upper 60s to low 70s Fahrenheit, with overnight lows dipping into the 40s or 50s. You should prepare for significant diurnal temperature swings as well as the high probability of spring rain showers, which can quickly saturate local trail surfaces. Elevation acclimatization is not a concern, as York sits around 400 to 600 feet above sea level. Because backyard formats demand robust logistical support, ensure your vehicle has room to transport a self-contained pit area, including canopy tents, cots, layered clothing, and adequate nutrition supplies for multiple days.
