The coolest of the fixed time series, the Fat Ox returns with a new venue at Estrella Mountain Regional Park for a 48-hour run fest! Participants choose between the 48 Hour, 24 Hour, 12 Hour, 6 Hour or 100 miler all on a 0.988178 mile certified loop! Run all day and night on this sidewalk path that winds around the turf area of Estrella Mountain Regional Park with the Estrella foothills as a backdrop.
Unfortunately, Nardini Manor had a scheduling conflict that is out of both of our control and we will be moving the 2022 Fat Ox Endurance Runs to nearby Estrella Mountain Regional Park. The start / finish line will be located near Ramadas 8 & 9 on the East side of the Turf area. The Aid Station tent will be easily accessible right on the course. The timing tent will be just North of the Aid Station with timing mats that you must cross each loop. You can setup your own pop-up tents, tables, chairs and aid right along the loop.
Camping will be an additional fee (details coming).
Anything else you may need to know is located on the Fat Ox website! Information on the website includes: course information, race day schedule, crew information, race perks, and more.
Race entries are non-refundable and non-transferable. For other options, please check out our Race Withdrawal Policy.
