2026 UW Medicine Seattle Marathon and Half Marathon
About the Event
Step into the heart of Seattle at the 2026 UW Medicine Seattle Marathon and Half Marathon, where tradition meets modern urban beauty. This race returns on November 29th, marking its place as one of America’s oldest marathons since 1970. The course is a marvel of scenic diversity, weaving through downtown landmarks such as the iconic Space Needle and historic Pioneer Square while offering breathtaking views of Puget Sound. Participants gather at Bell Street Park for the start, just west of Pioneer Square. As the race commences early in the crisp fall morning (temperatures ranging from 6°C to 11°C), runners enjoy a comfortable pace through Seattle’s vibrant streets before tackling the challenging hills and waterfront views that are quintessential to the city's charm. The atmosphere is electric, with spectators lining the route to cheer on participants. This marathon transcends mere physical exertion; it is an endurance test of support and camaraderie among athletes of all abilities. The event has a rich history of bringing together local communities and regional runners for over five decades, making it more than just a race but a cherished tradition. For those running the Full Marathon (42km), the course offers a mix of urban streets and scenic routes before looping back through downtown Seattle to conclude in Pioneer Square. The Half Marathon (21km) follows a similar path with its own unique blend of cityscapes and waterfront vistas. Both distances are designed for diverse runners, ensuring that every participant can find their perfect pace. Aid stations are strategically placed along the route to ensure hydration and nutrition needs are met during the journey. Special features include pacer support for sub-elite and elite runners, providing tailored guidance as needed. Virtual options allow participants unable to attend in person to join the race remotely. Weather on race day is mild with an average temperature of 8°C and low humidity levels at around 65%, making it ideal conditions for a run through Seattle’s historic neighborhoods. The forecast predicts clear skies throughout, ensuring optimal visibility and comfort as runners traverse the city's iconic landmarks. Registration fees vary based on participant type, starting from $39.91 for support runners to $99.16 for full marathons. Participants can register online at https://raceroster.com/events/2026/112954/2026-uw-medicine-seattle-marathon-and-half-marathon. Bibs will be available one week prior to the event in Pioneer Square, requiring valid photo ID and any necessary access codes or proof of eligibility. Participants should gather at Bell Street Park by 6:00 AM for an official start time of 7:00 AM. The race is open to runners aged 13 and over; first-timers are encouraged to familiarize themselves with the route beforehand. The UW Medicine Seattle Marathon and Half Marathon is a testament to the city's enduring spirit, blending historic significance with modern urban beauty. It stands as an event that not only showcases Seattle’s charm but also supports local communities through charitable efforts. This race is highly recommended for anyone looking to run in one of America’s most beautiful cities while contributing positively to its vibrant running community.
