Event overview
The Friends of Yellow River State Forest Trail Run/Walk is scheduled for Friday–Saturday, May 8–9, 2026, at Yellow River State Forest in Harpers Ferry, Iowa. The event includes these distances:
- Friday 5K (trail)
- Saturday 5K (trail)
- 10K (trail)
- Half-marathon (trail)
This is the seventh annual edition. Races will be timed. Because existing trails are used, course distances are not exact.

Prizes will be awarded for first through third place in those divisions; winners receive a canvas photograph from within the state forest.
