That map represents the West Seattle/South Park leg of a run we have just learned about via this announcement:

Residents are invited to cheer Marines from Always Brothers as they run 100 miles Aug. 10 and 11 from Seattle to Orting and back to honor military heroes from Washington State and to raise money for research of brain diseases and injuries experienced by veterans.

A group of Marines and civilians, some local and some from other parts of the U.S., will depart Leschi at 6 a.m., Aug. 10, and run through Mercer Island, Renton, Maple Valley, and Enumclaw before stopping at the Washington State Department of Veterans Affairs Soldiers Home in Orting. After a short break there they’ll continue along the outskirts of Puyallup and on through Sumner, Auburn, Kent, Tukwila, South Park and West Seattle, where they will be joined by a police escort as they cross the West Seattle bridge and finish, as a group, at CenturyLink Field at 9 a.m., Aug. 11.

This is the third year Always Brothers, a non-profit fraternal organization made up of Marines, other veterans, and their supporters, has hosted a 100-mile, 24-hour ultramarathon to benefit Marines and their families. This ultramarathon, unique in that it is not a race, will raise money for One Mind for Research™, a Seattle nonprofit dedicated to curing brain diseases, including traumatic brain injury (TBI) and post-traumatic stress (PTS).

“My original inspiration for working to improve diagnostics and treatments for brain injuries was the incredible number of soldiers returning from the wars in Iraq and Afghanistan with TBI and PTS,” says ONE MIND’s CEO Gen. Pete Chiarelli (Ret.), Seattle native and former Vice Chief of Staff of the United States Army. “We are proud to be supported by veterans’ organizations like Always Brothers to aid our mission of dealing with these ‘invisible wounds’ in both the military and civilian populations.”

Some runners will run the entire 100 miles while others will run as part of a team, with each team member running 5 to 25-mile legs. No matter the distance each participant runs, the ultramarathon is not a race. Participants will stick together the entire way, raising awareness of brain diseases and the stigma associated with them.

“Running 100 miles in 24 hours won’t be easy, but it’s nothing compared to what soldiers with PTS and TBI face,” says Marine Dan Neilsen, Maple Valley resident and vice president of Always Brothers. “We invite anyone and everyone to cheer us along the route, come to the north plaza of CenturyLink Field at 9 a.m. on Aug. 11 to watch us finish, or support the run financially at active.com/donate/AlwaysBros100OneMind.”

People interested in supporting virtually, or following the runners online can receive social media updates using the hashtag #100forONEMIND on Aug. 10 and 11.

As you can see in the map above, the West Seattle leg will primarily be on West Marginal Way SW, and organizers estimate they’ll be in the vicinity around 8 am August 11th, a week from this Sunday.
