Sycamore Canyon 100k / 50K / Half

Sycamore Canyon 100k / 50K / Half is held in Poway, California, on February 27, 2027, organized by Dirty Feet. Three trail distances are offered: a 100K (62 miles), a 50K (31 miles) and a half marathon (13.1 miles). Start times were not published at the time of listing.

This event covers a wide progression in a single day: the half marathon is a good first trail race, the 50K is a solid first ultra, and the 100K suits runners who already have a 50-mile or several 50K finishes behind them. For the 100K, plan on a 16- to 20-week build with back-to-back long runs, rehearsed fueling and steady hill work. The 50K needs 12 to 16 weeks with a long run peaking at about 20 miles, and the half marathon can be prepared in 8 to 10 weeks. San Diego County canyon trails usually mix fire roads and rocky singletrack with real climbing, so choose shoes with protection and train on ups and downs rather than flat paths.
