Pasadena 50K Relay & 50K Solo, May 24, 2026

The event takes place on Sunday, May 24, 2026, at Hahamongna Watershed Park, 4550 Oak Grove Drive, Pasadena, CA 91103, United States. It is presented as a set of running options on the same day at this park location.

The program includes a team relay and individual distance options. The relay is structured for teams of up to five runners and is intended for groups such as friends, family, or run club members to share the distance. The 50K Solo is offered as an individual ultramarathon-distance option for runners who prefer to complete the full course alone.

A shorter distance is also part of the program. The 10K option is presented as a Fun Run or Challenge that allows solo runners to participate without joining a relay team.

Participants should expect distinct entry categories for team and solo efforts and a mix of relay and solo formats on the same day. Specific course details, aid station locations, and event rules are not provided in this description. Visit the organization's website for the most recent information.
