Bad Ass Backyard Ultra

The Bad Ass Backyard Ultra (B.A.B.U.), held on March 28, 2026, in Rio Linda, CA, offers a unique challenge that transcends traditional race distances. Set at Dry Creek Parkway in Northern Sacramento, this event adheres to the classic backyard ultra format, where runners complete continuous 4.16-mile loops ("yards") within a one-hour time limit. The race continues, hour after hour, until only one runner remains to complete a final loop, making every other participant a "Did Not Finish" (DNF) by design. This compelling format tests not only physical endurance but also mental fortitude, fostering a unique communal yet competitive atmosphere where runners constantly face off against the clock and themselves.

The course at Dry Creek Parkway is notably flat, featuring approximately 30 feet of elevation gain per loop, making it a "pancake flat" experience ideal for pushing your limits. The early miles of each loop may be exposed, potentially presenting warmer conditions, while later sections offer welcome shade under tree cover as the trail winds through farmland. A dedicated start/finish and pitting area, located northwest of the main parking lot, provides essential support with electrolytes, gels, and other typical aid station provisions. Participants are encouraged to set up their own tents and pop-ups for close-proximity crewing, though aid is strictly limited to the pitting area between loops.

As an affiliated Backyard Ultra event, B.A.B.U. offers runners the exciting opportunity to earn a spot on a National Team for the Satellite Team Championships and potentially the World Individual Championships at Big's Backyard in Tennessee, adding a significant competitive layer to this endurance challenge. Typical race day conditions in late March include comfortable highs around 68°F and lows around 44°F, with a minimal 11% chance of precipitation, providing generally favorable weather for sustained effort. Whether aiming for a 6-hour personal best, a 12-hour milestone, or to be the last runner standing, the Bad Ass Backyard Ultra promises an unforgettable and truly demanding experience.
