The course

Where it goes point to point · 10 aid stations · rust marks a stop your crew can reach

Point-to-point from downtown Boonsboro to Springfield Middle School in Williamsport, in three distinct sections. Miles 0-2.5 are road, climbing onto the Appalachian Trail. Miles 2.5-15.5 follow the Appalachian Trail's rocky ridge singletrack (with about 2 miles of pavement between 3.5 and 5.5 mi), gaining 1,172 ft in the first 5.5 miles and then dropping over 1,000 ft in a series of switchbacks around mile 14.5 down to Route 340 and the C&O Canal. Miles 15.5-41.8 are the flat, unpaved, vehicle-free C&O Canal towpath (26.3 miles). The route leaves the towpath at Dam #4 and follows gently rolling paved country roads for the final 8.4 miles (41.8-50.2) to the finish.

The race

What this one is

A 50.2-mile point-to-point race in three distinct sections: road out of downtown Boonsboro onto the Appalachian Trail's rocky ridge singletrack (miles 0-15.5), the flat unpaved C&O Canal towpath along the Potomac (miles 15.5-41.8), and gently rolling paved country roads to the finish at Springfield Middle School in Williamsport (miles 41.8-50.2). A 6:30 a.m. mass start and a 13-hour time limit.

First held in spring 1963 as one of many 50-mile events staged nationwide after President John F. Kennedy challenged his military officers to match a physical-fitness standard Theodore Roosevelt had set for his own officers decades earlier: covering 50 miles on foot in 20 hours. Most of the nationwide JFK Challenge races were never held again after Kennedy's assassination in November 1963. The Washington County, Maryland event renamed itself from the JFK 50 Mile Challenge to the JFK 50 Mile Memorial in 1964 and, per the race's own history page, is the only original JFK Challenge event still held every year, which is the basis for calling it America's oldest ultramarathon. It describes itself as, in spirit, a military race, and awards the Kennedy Cup each year to the top-finishing military team.

Crew rules
Personal handlers/crew are allowed only at three race-designated points on the course: the Weverton Cliffs exit (~mile 15), Antietam Aqueduct (mile 27.3), and Taylor's Landing (mile 38.7). The race asks crews to leave general course support to official volunteers where possible, citing congestion concerns from local police and the National Park Service, and requires crews at the designated points to yield right-of-way at all times to Park Service personnel, officials, volunteers, participants and vehicles. Vehicle traffic on the final 8.4-mile road section is restricted between 11:00 a.m. and 7:30 p.m. on race day to race organizers, law enforcement and local traffic only; handlers/crew are not allowed on that final section at all, and a runner whose crew violates these rules can be disqualified. No bicycle handlers/crew are permitted anywhere on the course. jfk50mile.org
Pacer rules
"Pacers and/or companions are no longer allowed at the JFK 50 Mile. Any participant accompanied by a pacer/companion (not officially entered in the event and starting from the beginning of the event) will be disqualified." jfk50mile.org
Drop bag rules
JFK 50 Mile does not offer mid-course aid-station drop bags. It provides a single "Bag Transport" service that carries one bag per runner from the start staging area directly to the finish-line area; runners are told not to leave valuables in it. jfk50mile.org
Cutoff philosophy
The entire field starts together at 6:30 a.m.; the start line itself closes at 6:35 a.m. There is a single overall 13-hour time limit (7:30 p.m.), enforced through nine intermediate cutoffs spaced along the course. The race states plainly that after 7:30 p.m. no one may remain on the course -- insurance and National Park Service permitting require it -- and any runner who reaches a cutoff late must withdraw there rather than continue. Sweeper vehicles carry anyone picked up on the course to Springfield Middle School, the same finish-area building everyone else gathers at. jfk50mile.org
