Official event pageWhat this race demands
The JFK 50 Mile requires sustaining forward progress over an 80.5 km point-to-point course that combines technical trail terrain with an extended flat towpath finish in late November.
Ultra Distance Endurance
Covering 80.5 km demands a high level of aerobic conditioning and muscular endurance to manage fatigue over many hours of continuous movement.
Terrain Transitioning
Navigating the Appalachian Trail section followed by the C&O Canal towpath requires the adaptability to transition from technical, undulating surfaces to a sustained, repetitive running surface.
Late Autumn Conditions
Racing in late November requires adequate cold-weather preparation and the ability to maintain thermal regulation through changing ambient temperatures.
Given the extended duration of an 80.5 km ultramarathon, athletes should aim for a consistent intake of 60 to 90 grams of carbohydrates per hour to maintain energy availability.
