Greeley, CO

Welcome to the fields! Jess’ Backyard Ultra is named after 11 women named Jess who gathered from around the US and Canada to run the first JBU. Their friendship and perseverance led to the creation of this event-- and now it you're turn to leave a mark! This farm course in Greeley, Colorado, will be used for both the day and night loops. The course varies as runners run along dirt byways, dirt roads, grassy areas, overgrowth passages, a railroad, and several small bridges. Each loop consists of approximately 70ft elevation gain in total. It is very runner friendly.
