Bikers, runners, children and adults will explore the Valley and have a blast downtown, when North Bend hosts the third annual Adventure Sport Festival and North Bend Traverse, 11 a.m. to 4 p.m. Saturday, Sept. 6.

The day includes the North Bend Iron Horse Traverse, a multi-sport adventure race starting on Snoqualmie Pass and finishing at the Adventure Sport Festival.

The Traverse includes a five-mile paddle on Keechelus Lake, a 27-mile mountain bike ride down the historic Iron Horse Trail, a road bike ride 24.5 miles through the Snoqualmie Valley, and a six-mile run on local trails. Participants trek four blocks to finish in downtown North Bend. Register at Northbendtraverse.com.

The downtown festival celebrates local businesses that cater to outdoor recreation. Planned are a 30-foot climbing wall, 22-foot slide, obstacle course, bungees, paintball and laser tag games. Downtown businesses are asked by the city to take part. Spaces are free, and available. To get involved, contact Stacey Cepeda at stacey.cepeda@encompassnw.org.
