Become a founding runner of a new trail running tradition at the Northland Arboretum.
Trail racing is back at the Arb.

For nearly two decades, the Arb was home to one of the Brainerd Lakes Area’s favorite trail running traditions, and we are excited to once again welcome runners to our trails with a new name and a new chapter for the future.
Participants can choose between a Half Marathon or 10K race, both taking place entirely on Northland Arboretum property.
