The Snoqualmie Valley Half Marathon is a scenic trail race through the heart of Washington’s agricultural Snoqualmie Valley, featuring flat gravel paths and a festive post-race atmosphere ([Orca Running](https://www.orcarunning.com/snoqualmie-valley-half/)).
Course Highlights
The Snoqualmie Valley Half Marathon course begins at King County’s Tolt MacDonald Park and primarily follows the Snoqualmie Valley Trail, offering a flat and fast route with minimal elevation gain ([Orca Running](https://www.orcarunning.com/snoqualmie-valley-half/)). Runners traverse a scenic gravel and dirt path that meanders through beautiful agricultural areas, providing views of lush farmland and forests ([Orca Running](https://www.orcarunning.com/snoqualmie-valley-half/)). The half marathon route is USATF certified and features aid stations located approximately every three miles ([Orca Running](https://www.orcarunning.com/snoqualmie-valley-half/)). This point-to-point-style out-and-back course is well-regarded for its serene atmosphere and natural Pacific Northwest beauty ([Find a Race](https://findarace.com/us/events/snoqualmie-valley-half)).
What Makes It Special
The Snoqualmie Valley Half Marathon is distinguished by its commitment to sustainability through Orca Running’s cupless racing initiative ([Orca Running](https://www.orcarunning.com/snoqualmie-valley-half/)). After the race, participants can enjoy a beer garden sponsored by Iron Horse Brewery, with all proceeds benefiting the Eastside Firefighters Benevolent Fund ([Orca Running](https://www.orcarunning.com/snoqualmie-valley-half/)). The event also supports the REI Cooperative Action Fund, which works to improve outdoor access for all people ([Orca Running](https://www.orcarunning.com/snoqualmie-valley-half/)). With its inclusive environment, the race offers pacers from the Seattle Green Lake Running Group to help runners achieve their goal times ([Orca Running](https://www.orcarunning.com/snoqualmie-valley-half/)).

Race Weekend Tips
Packet pickup is available at REI Bellevue on the Thursday before the race or at the start line on race morning ([Orca Running](https://www.orcarunning.com/snoqualmie-valley-half/)). As this is a cupless race, participants must bring their own hydration vessel, such as a handheld bottle or hydration pack, to use at aid stations ([Orca Running](https://www.orcarunning.com/snoqualmie-valley-half/)). Parking is available at Tolt MacDonald Park and Tolt Middle School, though carpooling is strongly encouraged due to limited space ([Orca Running](https://www.orcarunning.com/snoqualmie-valley-half/)). The weather in June typically ranges from 60°F to 88°F, so runners should prepare for potentially warm conditions ([RaceRaves](https://raceraves.com/races/snoqualmie-valley-half/)).
