The Snoqualmie Valley Half takes place on June 20, 2026, in Carnation, WA. The race starts and finishes at King County’s Tolt MacDonald Park. Distances offered:

The event supports the Issaquah Food and Clothing Bank. Registrations are non-refundable and online pre-registration closes the day before the race.
Course and logistics
Both courses use the Snoqualmie Valley Trail and a connector trail along the Tolt River. The route leaves Tolt MacDonald Park, joins the Snoqualmie Valley Trail at about mile 1.25, follows an out-and-back format, and finishes at the park. The courses are USATF certified (Half: WA16003RMB; 10K: WA16002RMB).
Aid stations for the half provide water, Tailwind electrolyte drink, and GU gels at about miles 2.9, 5.9, 7, and 10.2. Portable restrooms are at miles 2, 2.9, 10.2, and 11.1. The 10K aid stations offer water and electrolyte drink at about miles 2.9 and 3.3, with a portable restroom at the aid station.
Orca Running runs the event cupless to reduce waste; participants are advised to use a handheld bottle, hydration pack, or a small reusable cup. Parking is at Tolt MacDonald Park, Tolt Middle School, and downtown Carnation; if the park fills, parking in Carnation requires about a 1/3 mile walk into the park. Packet pickup options include mailed bibs (fee $4.50), race morning pickup, or pre-race pickup at REI Bellevue. Awards are given to the top three overall in male, female, and non-binary categories by gun time and to age groups in five-year increments; awards must be picked up at the race.
