Friends of the Wissahickon Kicks Off 8th Annual All Trails Challenge this August

Explore and Support Wissahickon Valley Park

PHILADELPHIA – July 26 – The All Trails Challenge (ATC) hosted by Friends of the Wissahickon (FOW) is back for an eighth season this August. The family-friendly event continues to grow in popularity over the years for two simple reasons: love for Wissahickon Valley Park and fun!

The ATC is more than a walk in the park. It’s a personal challenge to discover new parts of the park’s 50+ miles of trails – on foot, bike, or horseback – at your own pace and your own schedule over 10 weeks. It’s a fun, family-friendly activity for all ages and fitness levels. And, with every mile, it’s an opportunity to contribute to FOW’s ongoing work to keep this urban green space clean, beautiful, and accessible, from clearing litter, invasive plants, and downed trees, to planting native plants, improving trails, and advocating for the watershed.

By registering as a Challenger, you’ll have the chance to meet like-minded adventurers, maybe experience the Wissahickon in a new way, and benefit the park by having friends and family support your ATC journey and the Wissahickon Valley Park.
