Clarksburg Country Run

Clarksburg Country Run is held in Clarksburg, California, on November 1, 2026. The 30K (18.6 miles) leads off at 8:00 a.m., followed by the half marathon (13.1 miles) at 8:30 a.m., which doubles as the PAUSATF Half Marathon Championship, then the 10K and 5K together at 8:45 a.m. Two kids fun runs, one mile and half a mile for ages 12 and under, start at 8:10 a.m.

The 30K is the distinctive option and an excellent stepping stone: long enough to test marathon pacing and fueling, short enough that it will not cost you weeks of recovery. Runners preparing for a winter marathon can slot it in as a long tempo. The half carries championship status, so expect a competitive front end, and pace your own race accordingly rather than chasing the group ahead.
