Introducing Groundwork — an eight-week guided running program moving city runners from pavement to trail.

Launching across Los Angeles, Portland, Montréal, and New York, the program is built around community, progression, and the confidence that comes from venturing beyond familiar routes.

Participants follow a structured training journey developed by mountain guide and trail runner Brenton Reagan, join weekly community runs led by local City Run Leads, and progress toward a finale trail run beyond the city. Because the trail has always been close.

Now you'll know how to move through it.
