'78 Mile Challenge

Official '78 Mile Challenge Logo
Join the National Park Service to celebrate Healthy Parks Healthy People by participating in the ‘78 Mile Challenge along the trails, roads, and waterways within Valley Forge National Historical Park.

Participants can run, walk, bike, hike, or paddle to complete the challenge. Keep track of miles you have accumulated in the park and when you reach that magic number - 78 - you will earn a special prize that places you in that elite group of outdoor enthusiasts. The number 78 recognizes 1778, the year George Washington’s army struggled, trained, and eventually persevered right here at Valley Forge.

The 2019 challenge begins on April 28 with the Rev Run event.

Kids Challenge

NPS staff will distribute mileage specific stickers for kids who complete 25 mi., 50 mi., and then 78 mi. It’s a great way for kids to monitor their progress!
BARK Ranger
B.A.R.K. Rangers are great companions for exploring Valley Forge!

Bring Your Pet Along for the Challenge

Dogs are great companions for enjoying the outdoors and are allowed on trails at Valley Forge National Historical Park. Canine companions can participate in this challenge. To complete this challenge, each participating pet must complete 78 miles in the park with their human companion. Every time your pet joins you on a walk, hike, or run in the park, simply check it off on the log form. When you’ve completed the challenge, add up your dog’s miles.

Prior to hitting the trail, please be aware Valley Forge offers a B.A.R.K. Ranger Program! This is a great way to get acquainted with park rules concerning pets. You can attend a B.A.R.K. Ranger event to get your pet sworn in and claim a small prize.

Please respect all visitors to parks and help protect site resources by following the park's pet policies:

  • Remember the B.A.R.K. Ranger pledge: Bag your waste; Always wear a leash; Respect wildlife; Know where you can go.

  • Dogs must be kept on a leash no longer than 6 feet at all times. Leashes protect pets from becoming lost, from hazardous wildlife encounters, and from scaring or threatening wildlife. Leashes also protect other visitors who may be afraid, allergic, or who do not want a pet approaching them.

  • Pick up your pet's waste. It is unpleasant to encounter and degrades the park's ecosystem.

  • Bring water for your pet to drink on your hikes. Streams may contain bacteria or parasites that are harmful to you and your pet.

As much as we love four-legged creatures, do not bring pets to public ranger programs; this avoids potential conflicts with other animals and respects other program participants.
