2026 Mercy Health Seaway Run

For over three decades, the Mercy Health Seaway Run has been a cherished tradition along the shores of Muskegon Lake in Muskegon, Michigan. The half-marathon course treats runners to expansive views of the lake, with a flat, fast profile that draws a competitive field. Recent years have seen around 315 finishers, hailing from approximately 18 states, making it a modest yet spirited gathering.

The race's growing popularity is reflected in its loyal following: nearly 29% of runners return for another year. The event maintains a friendly, community-driven atmosphere, with a focus on personal achievement. While the course is primarily road, the lakeside scenery and welcoming vibe make it a hidden gem in Michigan's running calendar.
