Saturday, January 31, 2026

Every year come rain or shine (usually rain!) on the last Saturday in January, we hold another fundraiser event. All donations benefit Northwest Harvest or other local food banks.  In previous years this event has been a point-to-point half marathon from Tukwila to Alki Beach. This year we have shortened the course to a 3.3 mile out-and-back segment that can be repeated until achieving the desired distance. The entire course will be clearly marked on paved trail without crossing any car traffic.
