Join us for the Ultralight Rock Run, a community trail run through Griffith Park in collaboration with Nike ACG, celebrating the launch of the all-new Nike ACG Ultrafly Trail shoe.

This guided 7.5-mile trail run begins Saturday morning at Satellite, moving from city streets into dirt paths and ridgelines as the day breaks. The route is designed to put ACG trail gear to work in real time—across mixed terrain, changing light, and technical sections. In use for the first time by the Usal and Satellite run community.

The run marks the opening chapter of First Light—a one-day community experience in Los Angeles celebrating the upcoming Nike ACG collection through movement, exploration, and time spent outdoors.
