STILLWATER — With the National Park Service Centennial celebration now over, Saratoga National Historical Park is looking forward to the next 100 years of stewardship.

Between May 1 and October 31, the public is encouraged to join a 100-Mile Challenge: biking or hiking the trails at the battlefield to accumulate 100 miles. Through this challenge people can enjoy the rich natural and cultural heritage of this local site as they explore their national park, plus get some exercise.

Anyone can take part in the challenge, from beginners to advanced hikers and cyclists, young and old, human and canine. Each participating pet must also hike 100 miles in the park with their human companion, following park pet policies.

Each participant (including pets)must register for the challenge by sending an email to: SARA_ This email address is being protected from spambots. You need JavaScript enabled to view it.morethan one person, specify the number of participants and their names.

Park staff will periodically send email messages with updates about this challenge, including news about upcoming hiking and biking events in the park, hiking and biking tips, and motivational thoughts. Email addresses will not be shared with others.

Each participant who completes 100 miles between May 1 and October 31 will receive an award for their achievement. Yet the real awards are new experiences and memories from adventures in a national park, of which there are more than 400 nationwide.

For more information about this challenge, call Park Ranger Megan Stevens at 518-670-2982 or visit the website www.nps.gov/sara.
