S**U prices increase September 28.

If your fall race season already has you thinking about what comes next, you’ve got a little over a week to lock in the current price for June.

5 Mile, Half Marathon, 50K, or 50 Mile. Run or Ruck. Runnable singletrack, well-marked trails, great aid stations and volunteers, and burgers waiting when you’re done.

And if you want trails on your calendar in more than one season, bundle S**U with Winter Trail Fest East or West in February and save 15%.

Fall race season has a way of getting you thinking about what you want to do next (sometimes before you've even run your fall race).

Maybe you're discovering you really like the trails. Maybe the distance that once sounded huge doesn't anymore. Or maybe you're realizing you don't actually want to go farther—you just want more days like this.

So what does your S**U look like next June?

5 Mile: I want a morning on the trails.

Half Marathon: Give me a substantial trail race, but I'm still going home for dinner.

50K: I want to find out what an ultra feels like—or come back for another one.

50 Mile: I'm ready to spend the day out there and see what I've got.

Four distances. Run or Ruck. No wrong answer.

"The volunteers and staff at the aid stations were incredible. The course was very well marked and made it easy to 'check out' but still have confidence I was moving in the right direction."

Our goal is a race day worthy of your hard training. We over mark the course. There are six aid stations you see each loop. 50 Mile and 50K runners have access to a drop bag. The cut offs are generous. And the volunteers always bring their A game on the grill, cowbell, AND hydration status checks.

If S**U is already on your 2027 calendar, you can make it part of something bigger. WTF prices increase Sunday night.

The WTF + S**U Trail Series connects our Michigan winter and summer trail races.

Start with Winter Trail Fest East on Feb. 13 or West on Feb. 20, then carry that training into S**U on June 12.

Run or ruck the 5 Mile or Half Marathon at WTF, then choose anything from the 5 Mile to the 50 Mile at S**U.

Register through the Series bundle and you’ll save 15% on each race. Complete both and you’ll earn two connecting finisher medals that link together magnetically.

Series bundle prices increase Sunday night, August 30 at 11:59 pm EST.

Links to register are in the comments. As we eventually say: WTF? Might as well S**U and RUN!

A lot of runners are training for a big fall race right now. S**U is in the rearview.

Maybe you're training for your first Half. First Marathon. Maybe you're transitioning into longer trail miles.

Two months ago at S**U, we watched people take all kinds of next steps: First trail races, first ultras, new distances, first ruck race, and another loop when they weren't sure they had one left.

And that's what we love about this race. All the different ways people challenge themselves and step outside their comfort zone.

You don't have to know exactly what next June looks like yet. But if this fall teaches you that you're ready for a little more, we'll have a 5 Mile, Half Marathon, 50K, and 50 Mile waiting at Sleepy Hollow.
