Gulliver's Run

Gulliver's Run is an annual fundraising event in Lewisberry, Pennsylvania, held on the trails of Gifford Pinchot State Park. It features a 5k trail run and a 3.5k walk for dogs and their human companions (participants may join without a dog). Proceeds benefit canine cancer research and treatment through a 501(c)3 nonprofit dedicated to fighting the disease.

Beginning in 2025, the walk distance was changed to 3.5k and named Maisy's March, with a slightly different course from the run. The event takes place on the first Sunday in November and is described as family-friendly with prizes, awards, and extra features. Visit the organization's website for the most recent information.
