Who: Travel solo or with a team of friends and family—anyone can be a Challenger. Create a fundraising page, track your miles, and help spread the word. Form a team to cheer each other on and multiply your impact. No matter your pace or experience level, there’s a spot in the challenge for you!
What: The All Trails Challenge is your opportunity to explore all 50+ miles of trails in the park—on foot, bike, or horseback—while raising funds to protect and improve our urban wilderness.
When: September 2nd – November 6th (Member Start: August 26th). Not a member, but you’d like a head start? Become a member here today. We’ll send you a link to register on the day of our member start.
Where: Every inch of the Wissahickon Valley Park trail system! Which, admittedly, is quite large! But don’t worry, you’ll have help. Challengers will be getting a brand-new, updated pocket map, as well as a printable ATC passport for you to track your miles manually.
Why: Because the Wissahickon needs your help—and you can make a real impact. Every dollar you raise goes directly into improving the 50+ miles of trails you’ll explore. Take in the views from the newly installed Lida Way Pedestrian Bridge, stroll down Forbidden Drive past the WPA-era shed at Bluestone Bridge with its restored roof, and hike along freshly rerouted sections of the Orange and Yellow Trails, designed for long-term sustainability. Every step you take fuels projects like these and helps conserve Wissahickon Valley Park for future generations.
How: This year, tracking your progress is easier than ever with our printable ATC Passport for manual logging and Strava integration for automatic mile tracking. Join our weekly guided hikes led by FOW Trail Ambassadors to connect with fellow Challengers and explore hidden corners of the park together. Come every week, and you’ll be well on your way to completing the challenge—one beautiful mile at a time!
