Run 4 UltraSound Half Marathon, 10K & 5K

Saturday, August 5, 2017 • Lakewood, WA • Course Map

Named for the historic fort that dates back to the late 1840s and was built here as part of the United States’ Pacific defense in what was then the Oregon Territory, Fort Steilacoom Park plays host to the annual late summer run 4 Ultrasound Half Marathon, 10K and 5K races, which are part of a weekend full of running, biking and walking events here.

The half marathon is open to both runners and walkers, and follows an out-and-back course that starts and finishes at the Fort Steilacoom playground.

From there, racers will make their way past and around the park’s dog park, past the campus of Pierce College and around the shoreline of Waughop Lake — all of this they’ll do twice, as the course follows a double-loop route.

The race’s organizers note that the courses are mostly flat, fast and fantastically beautiful with one memorable hill (make that two for the half-marathon). The course is a combination of trail and pavement, and is well-marked with signage and course monitors; runners can expect to see plenty of water stations out on the course.

There will be a free pancake breakfast, event photo and post-race massages for all paying registrants (kids 10 years old and under are free). For half-marathoners who like or need extra time to complete the race, there is also an unofficial early start, about one hour before the runners begin.

    My name is Elizabeth Oosterhout and I am interested in running the 5k on August 7th at your Run4Ultrasound event. For some reason the registration link does not work when I click on it – the Run4Ultrasound official website is down. Are you able to send me another link so that I can register for the run?

    Thanks and looking forward to hearing from you soon!

    These fees are incorrect. They are actually $30/$40/$50 including the (not optional) T-shirt. Registrants should also be aware that this organization is raising money for an anti-abortion cause.
