The Allegheny 100 Challenge is an unsupported endurance hiking challenge where participants attempt to traverse 25, 50, 75, or 100 miles of the North Country Trail through Pennsylvania's Allegheny National Forest within 50 hours.
What this race demands
The Allegheny 100 Challenge requires athletes to traverse up to 100 miles of unsupported trail within a 50-hour window.
Extended Endurance
Covering a distance of 160.9 km on foot demands prolonged continuous movement and rigorous pacing over multiple hours and terrain.
Self-Sufficiency
The unsupported nature of the event requires athletes to carry and manage all necessary gear, hydration, and nutrition independently between resupplies.
Fatigue Resistance
Operating continuously toward a 50-hour time limit places heavy demands on muscular durability and sleep management.
A continuous intake of 45 to 60 grams of carbohydrates per hour is recommended to sustain energy over the multi-hour duration.
