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, natural surface, single-track trails 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. In 2017, runners forded the Patapsco River on foot, and the river crossing will be back in 2019, pending park management approval. You will hardly believe you are just minutes from busy downtown Baltimore!
Course highlights include Cascade Falls, the ruins of the Orange Grove Flour Mill, as well as the Avalon Nail and Iron Works ruins. Not to mention gorgeous views of the Patapsco River throughout!
