Relay Iowa : June 12-14, 2026

Relay Iowa is a 3-day, 24 hours a day, 339-mile team relay across the state of Iowa. Teams of up to 12 runners share the distance by planning and running legs in rotation while teammates travel ahead by vehicle. Example vehicle arrangements mentioned include two 15-passenger vans or three smaller vehicles. Teams run through a variety of surfaces and settings, including gravel roads, winding two lane roads, farmland, and forest, and they progress day and night before finishing the full course together.

The route includes sponsored pit stops and checkpoints where participants may receive a hot meal, a quick shower, or a comfortable floor for a nap. Registration is organized by a team captain who creates a team and enables others to join; a free agent portal is available for those seeking a team. Event resources include a Survival Guide and captain resources to help teams plan their legs and logistics. Fundraising for local Iowa charities and Restoring Hope International is part of the event experience. Visit the organization's website for the most recent information.
