Fat Ox
November 22nd 2024

We beefed up the original Ox to bring you 6, 12, 24 or 48 hours of ultra fun. While previously held at Nardini Manor, this year’s event will be held on a 1 mile concrete loop at Estrella Mountain Regional Park.

Run your own experiment and push beyond your limits on the USATF Certified 500 meter course.  It’s perfect for your first ultra, your first 100 mile, or your own personal best; a 48 hour time limit to discover your inner animal! 

We’ll have a fully stocked aid station directly on course and you can setup trackside for ultimate convenience. Camping will be available for an additional fee on site.

Invite your family and friends to spectate, cheer and participate.
