Frightening 4k - Anchorage

Frightening 4k - Anchorage takes place in Anchorage, Alaska, on October 31, 2026, with a single 4K starting at 11:00 a.m. The event is put on by Skinny Raven, and the unusual distance, roughly 2.5 miles, sits between a fun run and a full 5K.

Four kilometers is short enough to run harder than you would over 5K, so if you want a fast one, warm up thoroughly and commit from the opening minutes. Halloween in Anchorage means limited daylight and the real possibility of ice or packed snow underfoot, so shoes with some grip are worth more than fresh racing flats, and a late-morning start puts you in the best light of the day. Dress in layers you can shed after the finish.
