IPA10K Brewfest & Beer Mile

IPA10K Brewfest & Beer Mile is held in Sebastopol, in Sonoma County, California, on October 31, 2026. Three road distances are offered: a 3K (1.9 miles), a 10K and a half marathon (13.1 miles).

A Brewfest at the finish serves a selection of local craft beer to participants, so the day leans festive as much as competitive. Pick the 3K if you are bringing family or want something short; take the 10K if you want a real effort without a long build; commit to the half marathon if you have been putting in weekly long runs. For that one, ten to twelve weeks with a long run reaching 10 or 11 miles is the sensible minimum, and it is worth rehearsing your race-morning breakfast on a couple of those long runs.
