Green Bay, United States of America · Sunday 17 May 2026
This race suits runners who want a solid spring tune-up without the brutality of a mountainous course. The flat to gently rolling terrain makes it a reasonable choice for first-time marathoners who have their base fitness in place, and for experienced runners targeting a time goal in late May. The modest elevation gain means you won't be grinding up relentless climbs, but don't mistake "gentle rolling" for boring. Those small ups throughout the race add up, and on a warm spring day in Wisconsin, they'll feel like more than nothing. If you're coming back from injury or looking for a confidence-building marathon before tackling something more demanding, this fits the bill. What you'll encounter is a Midwestern road marathon that doesn't offer much shade or terrain variation to keep your mind entertained. May in Green Bay can be unpredictable. You might get perfect running weather, cool and dry, or you might face humidity and warmth that turns the second half into a genuine grind. The course's mostly flat character means you won't get the mental boost of descending into a finish; instead you'll be maintaining effort for the entire second half when your legs are already tired. The surrounding landscape is pleasant enough but won't distract you from the work at hand. This is a race that rewards discipline and honest training rather than one that masks poor fitness with dramatic terrain or spectator energy.
