Terrible, Horrible, No Good, Very Bad Day 50K

The Terrible, Horrible, No Good, Very Bad Day 50K is a unique trail running event set for March 29, 2025, in Los Gatos, California. This non-supported, fatass run features challenging options, including a 50K with 10,900 feet of elevation gain, a 30K fun run, and a 10-mile Puppymeat run. Participants are encouraged to bring their own supplies, as aid stations are minimal.

The event aims to raise funds for Healing Hounds Dog Rescue, with a portion of the registration fee supporting this cause. Runners can start at their convenience, with a group start available for those who prefer a communal experience. Visit the organization's website for the most recent information.
