Dirty December Trail Run
This trail event in San Diego, CA on December 20, 2026 includes multiple distance options and a new timed hill-climb format. The organizer lists Marathon, Half Marathon and 10K courses alongside a Hill Climb 6HR event. Registration closes on December 18 at 11:59 PM PT.
The event has a holiday theme and includes a costume contest with two award categories: solo costumes and team costumes. The description notes a relaxed, low-key atmosphere and a best costume award for winners in those categories.
The Hill Climb 6HR asks runners to repeat an up-and-down loop of Cardiac hill. Each lap is about 2.5 miles (down then back up), and cumulative lap distances are tracked in 2.5-mile increments (2.5, 5, 7.5, 10, and so on). Winners of the 6HR Hill Climb receive King and Queen of the hill awards.
