Kicking off at 8:00 p.m. on Friday, June 19, the Firefly 3K offers a fun fitness challenge and a chance to enjoy stunning sunset views at The Morton Arboretum.
The Firefly 3K course will follow the main paved road on the Arboretum’s East Side, moving through the Arboretum’s tree and plant collections, and down Frost Hill. The course is relatively flat and well-suited for runners, walkers, and wheelchair users of all experience levels.
Highlights
Participants can run the Firefly 3K at the Arboretum or participate virtually by completing the course distance at another location and logging the results online.
All Firefly 3K race participants will receive branded Firefly 3K apparel.
Participants are invited to attend an evening postrace party with a live DJ, a disco ball, and refreshments.
