Become a founding runner of a new trail running tradition at the Northland Arboretum.
Trail racing is back at the Arb.
Join us for the inaugural Grow Wild Trail Run at the Northland Arboretum on Saturday, August 22nd. 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.

10K Start Time: 8:00 AM

From Endurance Grid
This race spans more than one sport — here’s a guide to each, so you can understand what’s involved and decide if it’s the right fit. For course distances, logistics, and race-day specifics, always defer to the race organizer’s event page.
From 5K to marathon, running races are the most accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
Running off-road — dirt, singletrack, and mountain paths — from 5Ks to ultras. The terrain, not the pace, is the whole point.
