Summer Trail Fest Ultra and Half Marathon

Summer Trail Fest Ultra and Half Marathon June 13, 2026 – Summer Trail Fest Ultra is your chance to STFU and run or ruck 50K, 13.1, or 5 Miles at Sleepy Hollow State Park.

Smooth trails, first-timer friendly, great vibes, generous cutoffs, and a post-race party worth going the extra mile.

Next Saturday we head to Sleepy Hollow for S**U!

Never run S**U before? Not sure where Laingsburg is? Think this race is only for ultra runners? Let's peek under the hood.

5 Mile, Half Marathon, 50K, & 50 Mile. Not everyone's running an ultra. Last year the Half & 5 Mile made up over 75% of the field.

Sleepy Hollow is about 28 minutes north of Lansing, an hour and fourteen minutes from Grand Rapids, and about an hour from Brighton.

The trails are smooth, course is well marked, and the aid stations are rockin'. The race starts and finishes near the beach and every finisher has a ticket to the cookout (burgers, hotdogs, sides) included in their registration. Running Lab and Altra will be on site to demo shoes and make friendship bracelets and hang out post race, and LCC Massage Students will be doing post race massage. Make a day of it with your favorite trail people!

It's shaping up to be a big club race too. We already have 24 teams signed up, including defending Trivium Club Cup contenders Romano Racing Co, Running Lab, and Playmakers.

The trails, the aid stations, the cookout, the people. It's shaping up to be a fun day at Sleepy Hollow. Registration link is in the comments.

Volunteers are a huge part of what makes S**U feel like S**U.

We’re still looking for a few people to help at registration, aid stations, the finish line, and the post-race picnic on June 13 at Sleepy Hollow State Park.

You don’t have to be an ultra runner to volunteer. Some of our best volunteers are friends, family members, local clubs, or runners taking a break from racing.

Aid stations keep runners moving all day. Finish line volunteers hand out medals and welcome people in after long hours on the course. Registration and packet pickup help the whole day start smoothly.

Volunteer perks — choose one:
• Race credit for a future Trivium race
• Donation to your club/group
• S**U singlet

Clubs also earn 5 points toward the Trivium Club Competition for each volunteer.

If you want to get in on the ultra race day love without racing, we’d love to have you out there.

Two weeks until S**U!

Some people have started the taper.
Some people are pretending they started the taper while secretly adding “just one more long run.”

Some people already have a pile of gels, salt tabs, sunscreen, bug spray, anti-chafe, and half-tested hydration packs sitting in the corner of the room.

And some people are already compulsively checking the weather. Don't do it. Seriously.

We’re getting close.

Registration’s still open. We still need volunteers. Athlete Guide is up. Clubs are padding their rosters. Crew group chats are getting active.

And if you’re tapering, resist the urge to suddenly become the most active person alive. Now is not the time to discover pickleball, install a home gym, or finally take up adult gymnastics.

This weekend's an important one for a lot of people training for S**U.

Ultra runners are getting into peak long run territory before the taper starts. Long hours on the trails. Early mornings. Figuring out what fuel still sounds edible after three hours.

Half Marathon runners are getting close too. Maybe not quite taper time yet, but close enough that race day starts to feel real.

And the 5 Mile runners are getting ready too. Some people will race it hard. Some will run it easy. Some will run or ruck it. Some will walk the whole thing and just enjoy being part of the atmosphere for the day.

That’s one of the nice things about the 5 Mile. You still get to spend the morning out on the trails and be part of everything happening at S**U, even if you’re not out there for 50 miles.

That’s part of what makes this race fun every year. Everybody’s showing up with a different goal and a different kind of day ahead of them. Everybody's part of the trail community.
