Registration for the 2026 Happy Little 5K opens Nov. 1
Get ready to run, walk, roll or hike!
The 2026 Run for the Trees: Happy Little (Virtual) 5K is officially scheduled for April 18–26. We're giving you a full nine days to complete your 5K at your own pace and location, making sure you can celebrate both Earth Day (April 22) and Arbor Day (April 24)!
Participants could choose their own pace and any outdoor location. For a $36 registration fee, participants received a keepsake Happy Little T-shirt, finisher’s medal, commemorative bib number and shipping.
The 2025 event raised more than $200,000 for tree planting and forest protection, with each state receiving funds proportional to its participation.
People around the world are familiar with the work and personality of Bob Ross, the American painter, art instructor and television host who in the ’80s and ’90s shared his love for painting and the environment with millions of viewers on the PBS show, “The Joy of Painting.” Ross was known for demonstrating seemingly simple brushstrokes that brought gorgeous landscapes – full of happy little trees – to life on the canvas.
The tree planting program
Launched in 2004 as a partnership with the Michigan Department of Corrections' Horticulture Education program, this tree planting initiative provided participants the training and job skills to grow seed from native trees found in Michigan state parks. Through funding provided by the Great Lakes Restoration Initiative, the program aimed to mitigate the loss of ash trees due to the emerald ash borer and equip participants with job skills.
In 2019, the program expanded into "Happy Little Trees," a collaboration between the DNR and Bob Ross Inc. to raise awareness about tree planting and forest protection. Funds raised support the purchase of native trees and shrubs, seed collection, and forest canopy protection within Michigan state parks.
Visitors to state parks where trees have been planted will see bright green "Happy Little Trees Ahead" signs to note the program's important contributions.
The program has produced more than 100,000 native plants, shrubs and trees since its start in 2004. With support from the Bob Ross partnership, more than 2,100 trees have been planted in 20 state parks across Michigan.
