If you want a race where the scenery does the heavy lifting while the terrain stays out of your way, this is it. It’s a classic Midwestern lakeside run—straightforward, scenic, and perfect for runners who hate chasing hills.
Trinity Health Seaway Run 2026 takes place on Saturday, June 27, 2026, in Muskegon, United States. You can choose from a Half Marathon, 10K, 5K, or a Community Walk, with a Kids Fun Run held the evening prior. The highlight is undoubtedly the shoreline stretch along Lake Michigan, making it a standout summer road event in the region.
Which distances should I pick?
The Half Marathon kicks off at 7:00 AM, making it the best bet if you want to beat the June humidity. The 10K follows at 7:45 AM, and the 5K starts at 8:00 AM. If you are looking for a serious challenge or a time trial, go for the Half; if you just want to soak in the lake views without the grind, the 10K is the sweet spot. There is also a Community Walk at 8:05 AM and a 1.2K Kids Fun Run on Friday evening.
What is the terrain like on the route?
It is a road event, and it is remarkably flat. Since the course hugs the shores of Lake Michigan, you won't be fighting significant elevation changes, which is a massive plus for anyone chasing a personal best. It’s scenic, but don't let the views distract you from your splits—it's a course designed for rhythm.
What should I expect to wear and how will the weather behave?
Late June in Michigan can be a wildcard. You can expect beautiful, breezy morning temperatures, but once the sun hits the pavement, it can get humid quickly. I’d recommend lightweight, moisture-wicking gear and perhaps a light singlet. The lake breeze is your best friend here, but don't rely on it to keep you cool if the humidity spikes.
What do I get for my registration fee?
The pricing is tiered: $90 for the Half Marathon, $65 for the 10K, and $45 for the 5K ($15 for kids). For these prices, you’re getting a race shirt, a finisher medal, a post-race treat ticket, and snacks at the finish line. It’s a fair deal for a well-organized community event, especially considering the scenic value. You can register via Runsignup ↗.
How do I get to the start line?
Muskegon isn't a massive international hub, so you'll likely fly into Grand Rapids (GRR) and drive about an hour west. For accommodation, look for hotels near Heritage Landing or in downtown Muskegon to avoid any morning transit stress. Most runners find the local setup easy to navigate once they arrive in the city.
