Hike, bike, run, and ride your way through the 50+ miles of trails in Wissahickon Valley Park – and support a unique urban green space while you do! The All Trails Challenge and it's challengers support FOW's mission to conserve the Wissahickon for generations to come!

It’s simple: from August 17th to November 30th, ATC Challengers make their way through every corner of the Wissahickon. ATC isn’t a race and you don’t have to be a conditioned athlete to take part – instead, it’s an opportunity to get back in touch with the beauty of the park. FOW members will be able to register for the All Trails Challenge beginning on August 17th and get a leg up on the competition – while August 31st will be the official start for everyone else.

Meet up with fellow Challengers on the trails and at ATC social events – and get friends and family to support your challenge (and the conservation of Wissahickon Valley Park) to win fabulous prizes and some of the very best swag the FOW shop has to offer. We can’t think of a better reason to get outside!
