Spartan Race - San Luis Obispo - Ultra, Beast & Super routes

San Luis Obispo's Santa Margarita Ranch will host this epic Spartan Weekend, drawing competitors from all over the world to partake in three awesome events. The courses will take you over rolling hills, through sprawling fields, past vineyards and old railway lines, all while in the shadow of the San Pedro National Forest.


In Spartan's longest race, the Ultra will combine the best of obstacle course racing with endurance running to bring competitors the ultimate physical and mental challenge. Competitors will be tasked to traverse 50K of Santa Margarita Ranch's stunning terrain, as they scramble over 60 obstacles in their search for victory.


For those looking for a shorter distance but a spectacular challenge, the Beast might be the event for you. 30 obstacles over the half marathon distance of 13.1 miles promises that all competitors will be pushed to the edge of their comfort zones, and blast through their limits as they clamber through the course.


If speed is the name of your game, take on the Super, which sees 25 obstacles packed into 10K of distance, offering a true athletic test of both strength and speed.

Kids Race:

Spartan Race isn't just for adults. The Spartan Kids Race offers three distances for the little ones in your life. Based on age, the races have obstacles in them just like the grown up versions, and will see your kids jump, crawl, and play their way through the course.

After the race, celebrate in style in the event village, where you and your fellow Spartans can swap war stories over a cold drink and hot food.
