Out & Back is an advanced trail running series presented by Usal and LSD Running, designed for experienced runners eager to explore Los Angeles’ diverse terrain. Taking place on the first Saturday of every month, each guided group run covers at least 10 miles with significant elevation gain, fostering endurance, camaraderie, and a deep connection to the trails.

Participants should be confident in their ability, maintaining at least a 10-minute-per-mile road pace, and come prepared with their own fuel and hydration. A lead guide and a secondary pace group will ensure a structured yet challenging experience, with bag drop and demo trail shoes available at no cost. Meet at 7:30 AM, depart by 8:00 AM—RSVP is highly encouraged!
