About the 2027 Grandma's Marathon
This entry is a charity bib, not a standard registration. You earn your spot in the marathon, the half marathon, or the shorter road race by raising funds for Semper Fi & America's Fund, an organization that supports critically wounded and injured service members and their families. The race weekend is based in Duluth, with distance options to suit different goals.
