The Indiana Department of Natural Resources and the Indiana Natural Resources Foundation welcome back the 2026 Happy Little (Virtual) 5K.

This year’s virtual run raised more than $41,000 for tree plantings and healthy forest initiatives in Indiana State Parks, with more than 2,300 participants.

The event is open to everyone, and registrants can complete their 5K anywhere outdoors – on foot, by bike, skate or paddle, or even using a mobility device – anytime between April 18-26, 2026, to encompass Earth Day (April 22) and Arbor Day (April 24).

For $36 per person, each participant will receive a keepsake Happy Little T-shirt, a commemorative bib number, and a finisher’s medal. Proceeds support tree planting and forest protection efforts in state parks.
