Way back in 2014 a brave group of runners gathered for the very 1st Blood Run.

Back then we only had two times: 12 & 6 hours, because who would want to run a 1.5ish mile loop longer than that?

Turns out, a lot of people! We’ve added a 36, 24, and 3 hour run.

If you run 100 miles in the 36 or 24 hour, you earn a buckle.

We’re a grassroots outfit. We don’t have corporate sponsors. We like to have fun and challenge you to test yourself.

The Blood Run at The Good Earth Farm

The Blood Run is a 36, 24, 12, 6, or 3 hour endurance run around The Good Earth Farm.

What you can expect

The Setting

The farm is located 4 miles south of Lennox, SD, which is about 20 minutes from Sioux Falls, SD. The farmers, Jeff and Nancy, have lived here since 2011. Both are recovering ultra runners from the time before online registrations, lotteries, and people referring to food as nutrition. The nearest hotel is in Tea, SD. There is also camping at the farm.

The Course

The farm sits on about 30 acres with a little creek running through it. There’s a bridge over the creek to keep your tootsies dry. The 1.5 mile course is a little gravel, a lot of grass (mowed path) and some dirt. You will run around the vegetable fields, across the pasture, onto a gravel road, and then back to the perimeter of the fields until you start it all over again!

    We don’t like to make rules about stuff like this—so someone can run/walk with you for a while. Just be mindful of other people on the course.

  • You can—here are a few things to keep in mind. If it’s hot (which it almost always is) there is very little shade at the farm. Your dog probably doesn’t want to run 36 or even 3 hours with you—so you will need to have a handler for it. Your dog must be on a leash at all times. We are an animal sanctuary where cats, chickens, geese, and the occasional deer run around freely. We also have two donkeys who’s purpose is to keep predators (like coyotes/dogs) at bay.

  • We keep track of your laps by putting a marble in a jar for each lap you complete. Once you finish your race, your jar of marbles are yours!
