Forbidden Run Fest

Forbidden Run Fest, staged by Uberendurancesports, takes place in Wissahickon Valley Park, Philadelphia, PA. The race offers 10K, 10 Miles, and a 13.1+ half-marathon option, all run entirely within the park's trail system. The course centers on Forbidden Drive, a smooth gravel and dirt trail with Mount Misery’s rocky uphill segment providing a challenge, plus rolling single-track and occasional paved sections for variety.

The event celebrates Philadelphia’s parks, featuring a post-race pizza party and live music, a finisher shirt, and awards for the top finishers. It is described as hiker-friendly with a generous time limit and multiple aid stops; bib pickup is on race day only. Visit the organization's website for the most recent information.
