How brutal is the terrain actually going to be?

It is 100% trail, so leave the road shoes at home. While you won't be scrambling over technical rock gardens, the course is defined by the glacial moraine topography. You are looking at significant vertical movement—roughly 4,670 ft of gain/loss for the 50K. The "runnability" refers to the surface (mostly double-track and gravel), not the gradient. Expect seven long, soul-crushing climbs per loop that drag you from the riverbank up to the oak savannas.

Should I sign up for the 25K or the 50K?

The 50K is the flagship here, offering UTMB qualifying points, which makes it the choice for serious ultra-distance aspirants. It’s a two-loop format (2 x 25K), meaning you get to revisit the terrain and utilize a drop bag at the halfway mark. The 25K is a single-loop affair that is still quite steep and serves as a great "entry-level" ultra for those who want the hill work without the double-loop mental fatigue.

Is it going to be a total furnace on race day?

Yes. It is the Fourth of July in Minnesota. Expect high humidity and temperatures that can easily climb into the mid-90s°F. This isn't a race where you can just "wing it" with a single handheld bottle. The organizers are bringing in 1,350 lbs of ice, which is a massive plus, but you must arrive with a solid heat-acclimatization plan and plenty of personal hydration.

What do I need to carry to survive the course?

This is a cupless race, so a reusable cup is mandatory. Crucially, the aid stations provide snacks, Coke, and ginger ale, but they do not provide gels or specialized sports drinks. You are responsible for your own fueling strategy. If you rely on gels, pack more than you think you need.

What happens once I cross the finish line?

There is no fancy podium ceremony or age-group prize money to chase, but the reward is decent: a wooden finisher medal and a post-race spread of Neapolitan pizza and canned beverages. It’s a community-focused vibe rather than a high-stakes professional meet.

How much is this going to cost me?

The 25K is $95 and the 50K is $115 (plus UltraSignup fees). Given the inclusion of UTMB points and the quality of the park setting, the pricing is fair. It’s a mid-range price point for a US trail race that delivers a specialized experience.
