The Experience
The Eisenbahn Trail Half Marathon, first run in 2020 and now in its fifth year, provides a unique out-and-back experience through Wisconsin's Kettle Moraine State Forest.
Runners will navigate a course built on a former railroad corridor, featuring 1.25 miles of paved asphalt at the start and finish, with the majority of the 21.1km course on limestone screenings. This relatively flat path, with minimal elevation change, is designed for speed, with a typical winning time around 82 minutes.
The race draws participants from about 11 states, with a median field size of approximately 307 finishers. While repeat-runner loyalty is around 8%, the growing field suggests increasing appeal. Post-race, participants can enjoy food at the start/finish line and receive finisher medals and t-shirts, with trophies awarded to the top male and female finishers.
