Course
The JFK 50 course
The largest and oldest ultramarathon in the United States, and structurally three races in one: a rocky Appalachian Trail section running from about mile 5.5 to mile 15.5, then 26.3 flat miles on the C&O Canal towpath beside the Potomac, then 8.4 miles of rolling country road into Williamsport. The towpath is dead flat and relentlessly repetitive, and it is where the race is actually decided.

- Late November in western Maryland is cold: starts near freezing, highs in the 40s, and wet leaves on the Appalachian Trail section early on. The canal towpath holds cold air and can feel considerably colder than the forecast.
What to train for
Flat, repetitive volume above everything.
The towpath asks you to hold one gait for 26 miles with no terrain variation to reset the muscles, which is a specific and trainable stress.
Include long, monotonous flat runs, and practise the technical trail descent early in the race so it costs you nothing later.
Sample week
A sample JFK 50 training week
A week from the middle of the build, about six weeks out. Your plan sets the real distances and paces from your own fitness and adjusts them every week as you train.
- Monday
- Rest, or 20 minutes of mobility
- Tuesday Key session
- Hill repeats: 10 × 2 min up a steady grade, jog back down
- Wednesday
- Easy run, 6 mi
- Thursday Key session
- Goal-pace run, 8 mi with 4 mi at race pace
- Friday
- Recovery run, 4 mi, or cross-train
- Saturday Key session
- Long run, 18–20 mi on trail, with as much climbing as you can find
- Sunday Key session
- Second long day, 10–12 mi easy on tired legs
Taper
Tapering for the JFK 50
Start the taper two to three weeks before race day. Cut your weekly volume by about a third, then by half in race week, and keep a few short efforts at race pace so your legs stay sharp. The course rolls, so keep one short session on undulating ground in the first taper week.
JFK 50 training questions
How long should I train for the JFK 50?
Most runners give a 50-mile race twenty to twenty-four weeks of focused training on top of a season of consistent aerobic mileage. The coach counts back from your actual race date, so if you have less time than that it builds the best plan the remaining weeks allow rather than pretending you have longer.
