The Iron Ranger Challenge is back for its 6th consecutive year! Over the last 6 years, we’ve had over 1,500 folks hike, bike, swim, or paddle 100 miles on Arkansas public lands. We’re so proud of all that you’ve explored and hope that you’ll join us again for another adventurous year.

The 2022 Iron Ranger Challenge will continue to hold true to its roots, complete 100 miles of physical activity on any public lands within the state of Arkansas and you are eligible to become an Iron Ranger. This means any activity you do in an Arkansas National Park, Arkansas State Park, Arkansas Game & Fish Commission lands, US Forest Service site, National Wildlife Refuge site, Army Corps of Engineers site, or city park can be counted.

Activities should be self-propelled so things like walking, running, hiking, biking, swimming, and paddling all count towards the 100 mile goal!
