Race Info

The Patapsco Valley 50K is a trail ultramarathon on the trails of Patapsco Valley State Park Avalon Area in Baltimore, Maryland. The race features plenty of scenic dirt single track with a few short sections on paved bike trail. The terrain is challenging but runnable with rolling hills throughout. The course has a handful of small creek crossings and can often be muddy in many places. You will hardly believe you are just minutes from busy downtown Baltimore!

Course highlights include Cascade Falls, Bloede Dam, which was the first submerged hydroelectric dam known to exist, Swinging Bridge, and the ruins of the Orange Grove Flour Mill and the small manufacturing towns of Orange Grove and Avalon, as well as the Avalon Nail and Iron Works. Not to mention gorgeous views of the Patapsco River throughout! Adding to the intrigue of this race is the fact that part of the 1999 movie The Blair Witch project was filmed at Patapsco Valley State Park!

Start/Finish Location

The race begins and finishes in the grassy field adjacent to shelter #105 in the Avalon Area of Patapsco Valley State Park in Arbutus, MD.


The race has continued to grow over the years where we have outgrown our ability to comfortably park everyone inside of Patapsco Valley State Park at the start/finish pavilion. This year, we will provide a shuttle to/from the S. Rolling Road Park & Ride (located at S. Rolling Road & 195). The shuttle takes ~15 minutes to drive from the Park & Ride to the start/finish.

Start Time & Cutoff
