THE WORLD'S LONGEST RELAY

A 24-hour, 3-day, 339-mile adventure run across Iowa with your friends (or complete strangers)!

RELAY IOWA | JUNE 6-8, 2025

HOW IT WORKS

YOU LOVE RUNNING. AND ADVENTURE.

You and up to 11 other teammates will set out Friday morning to run across the state of Iowa. 339 miles together. Whether it's two 15 passenger vans, or three smaller vehicles, you will each plan out the legs of the relay. As one group runs, the other(s) sleep, eat, and move ahead to the next meeting point. Along the way, you grow closer to each team member, experience the beauty of running day and night, and cross the finish line with your team after 339 miles.

WHERE YOU WILL RUN

THE ROUTE

Over the course of the 339 miles, you will encounter gravel roads, winding two-lanes, farmland, forest, and much more. As you relay across the state of Iowa with your team, there will be sponsored pit stops and checkpoints along the way. At these locations, you might get a hot meal, a quick shower, or a comfortable floor to have a nap. The route is also where the adventure comes in. You might be craving a post 3-mile slice of breakfast pizza, or find a nice shady spot for some team yoga. We encourage teams to take it all in, plan their own stops, and make this their own (while following the route of course!) View all locations on the map to the right, or in the Relay Iowa Survival Guide!

HOW TO PARTICIPATE

Gather your team, start training, and get ready for an adventure across Iowa.

01

GATHER YOUR TEAM

Teams can have up to 12 runners. You can run it with less, but for first time teams, we recommend at least 8. Think of your friends, family, other running clubs you can get involved with. Don't want to put in the work to gather a team? No worries, join a team through our free agent portal!

03

RUN, SLEEP, EAT, REPEAT.

You have been training for this. You gather with your team, ready to run across Iowa. Enjoy the sunrises, sunsets, late nights and early mornings as you run 339 miles with your team. 

02

REGISTER YOUR TEAM

Once a team captain registers and creates a team, they can have other runners sign up. Then, you will want to study the Survival Guide and our captain resources to plan how you will tackle those 339 miles.

04

CELEBRATE!

You just ran the World's Longest Relay Run, traversing 339 miles as a team, day and night. Get some sleep, celebrate, and reflect on the amazing memories you made with your team!

I’ve run Relay Iowa 2 years in a row and have loved every minute. Each year was a different team environment that I wouldn’t change for the world. I love the non-profit fundraising part and the organization during the event. Keep up the good work!

WHY RUN

There are a lot of reasons to run Relay Iowa, much of which you will have to find for yourself (that's part of the fun!)  Here are a few reasons we know people run. To conquer the World's Longest Relay. To challenge themselves. To find community. To make running a big adventure. Also, to give back.
