The road to your own record

The city you want to run becomes your next trip.
THE DREAM
Runners follow the Black Forest Trail deep in the Pennsylvania Wilds.
Cresting each climb reveals surrounding peaks and valleys,
and the course passes through pine plantations and forests of towering hemlock and red spruce in turn.
It's held at peak fall foliage.
Picture the course in advance
and find the pace that fits you.
Streets lined with cheers, runners all around.
You'll be part of that scene.
Take it slow with the finish still in you,
and meet the city all over again.
From the joy of finishing to the tough moments — read what runners wrote themselves.
“I ran the race in an odd year (course flips direction every year so the 2024 loop is the opposite way) and I was surprised how much running I got to do during the early parts of the race.”At Pennsylvania's Black Forest Ultra 100km, the runner found more of the course runnable than expected, particularly the early trails. The big climbs were steep, but flat sections gave the terrain a distinct variety.
We translated a short line from each public race report and summarized the experience. Finish times are as stated by the author, and past editions may differ from this year's weather and operations.
