ASTORIA — Lewis and Clark National Historical Park will host the first of a trail run series on Saturday, March 21 to “bid adieu” to winter at Fort Clatsop and greet the arrival of spring.

The Lewis & Clark Trail Series includes three different exhilarating events along beautiful trails through forest landscapes, complete with a welcoming and friendly race atmosphere. All events are open to walkers and runners of all ages and provide the opportunity to experience the Northwest coast the way people have done it for thousands of years: on footpaths.

The first event in the Lewis & Clark Trail Series takes place at 10 a.m. Saturday. Come for either an approximate 5K or 10K course that features the Kwis Kwis Trail. The 10K run will include a two-mile stretch of brand new trail. The start/finish line will be at the Fort to Sea Trail parking area off Fort Clatsop Road. Allow time to park at one of the Fort Clatsop Visitor Center parking lots, check in at the visitor center, and then hike 0.5 miles of the Fort to Sea Trail to the starting point as a warm-up.

Pre-register in person, or register that morning from 9 to 9:30 a.m. The cost to participate is the purchase of a $10 Annual Park Pass that grants entry into all of the 2015 Lewis & Clark Trail Series events. Registration is free with any pass that allows entry into national parks. Participants younger than 18 also need their parent or guardian to sign the registration.

The Lewis & Clark Trail Series is sponsored by the Lewis & Clark National Park Association, which supports park education and interpretative activities. The other events in the series are scheduled for June 20 and Sept. 26. For more information, call the park at 503-861-2471.
