The San Diego City Slam is composed of the following San Diego ultra events:

The Ranch 50k (Second Wind Trail Running, February)

Mission Trails Twilight Runs 50k (Endurance Race Series, May)

Black Mountain 50k (June)

Lake Hodges Trail Festival 50k (Elevation Culture, October)

To be eligible for recognition, participants must complete all San Diego City Slam events within a 12-month period. You may start with whichever race you choose: each event offers a distinct challenge, and completing them all within 12 months represents a significant achievement — and great preparation for the San Diego Ultra Slam!
