The Rachel Carson Trail Challenge is a 37-mile endurance hike that spans nearly the entire rugged Rachel Carson Trail, held on the Saturday closest to the summer solstice. Participants will begin their journey at sunrise in North Park and trek towards Harrison Hills Park, with a completion deadline by sunset, allowing just over 15 hours to finish. This event emphasizes endurance over competition, encouraging hikers to complete the trail within the specified time. The course showcases the stunning beauty of the trail, with its challenging terrain providing a true test of stamina. While the primary event is quite demanding, there are shorter options available that do not exceed 50 kilometers; however, the focus remains on the full challenge, creating a memorable experience for those who embrace the long hike.
