Welcome to Midsommar: Sun Loop Ultra, a late-July test of pure grit, endurance, and psychological fortitude.

Set during the absolute peak of the summer heat, Midsommar challenges runners to conquer a deceivingly straightforward 5-mile loop under the relentless July sun. Whether you are tackling your very first 5-mile trail run or attempting to survive 100 miles in the midsummar glare, every single distance will test what you’re made of.

There are no dark forests to hide in, no cool mountain breeze coming to save you—just you, the loop, and the sun.

☀️ The Challenge
You will run a repeating 5-mile loop starting and ending at The Maypole—our central hub, main aid station, and race party HQ.

Because every loop brings you right back through the heart of the event, you’ll never be more than a few miles from ice, liquid hydration, and a cheering crowd. But don't let the convenience fool you: stepping back out into the heat for one more lap is where the real mental battle begins.

Distances Offered

5 Miles (1 Loop) - A fast, fiery summer dash.

15 Miles (3 Loops) - The ultimate hot-weather workout.

50K (6 Loops + short spur) - A true test of heat management.

50 Miles (10 Loops) - Halfway to insanity.

100 Miles (20 Loops) - The ultimate Midsommar rite of passage.

Night 5 Mile - Suns gone but the loop isn't

Night 50k - Knock the 50k out at night or maybe add it on from another morning distance
