Forbidden Forest 30 Hour Ultra

The Forbidden Forest 30 Hour Ultra is a trail running event held at Roosevelt Forest in Stratford, Connecticut. Participants navigate an irregular loop measuring 2.23 miles in length. The course features typical New England terrain, including roots, rocks, and rolling hills, with a maximum elevation gain of 201 feet per lap. One specific hill on the course is known as "OMG." The trail is marked with flags and signs for navigation.

Participants have a total of 30 hours to complete as many miles as they choose. The event offers several distance milestones, and those who complete 45 loops (approximately 100 miles) receive a finisher buckle. Awards are presented to the top three male and female finishers based on the total mileage achieved within the 30-hour time limit.

Available distances and milestones include:

  • 26.2 miles

The event provides a single aid station located in a pavilion, offering hydration, GU, and a variety of snacks. Specific food service includes sandwiches in the afternoon, pizza and potatoes in the evening, and breakfast sandwiches on Sunday morning.

The race allows one pacer per runner once the participant has reached 60 miles or starting at 2:30 am on Sunday. Pacers must register, sign a waiver, and pay a fee. Personal areas for runners can be set up in a designated lot across from the pavilion. Small parking facilities are available on-site, and the use of hiking poles and earbuds is permitted.
