San Luis Obispo Spartan Trifecta Weekend

San Luis Obispo County, or SLO CAL, offers sunny days and star-studded nights, which await you at Santa Margarita Ranch, one of the largest operating vineyards in an area known for its wine production. Dash through the rows of grapevines amid fall colors and in epic open landscapes, surrounded by the towering Los Padres National Forest. On the course, you'll take in views of wildlife and a fossilized oyster bed on-course. This is one of our faster Ultras and a perfect destination for first-time racers to take on the 50K challenge. Plus, the San Luis Beast is the fifth Age Group National Series race. Compete against the top Age Group athletes from around the country and earn points based on your finishing position.

This event is a Trifecta Weekend, giving racers the ability to complete a Trifecta (Sprint 5K, Super 10K & Beast 21K) in just one weekend, plus you will qualify for the 2023 Trifecta World Championship in Sparta, Greece. Get the Pass Here.

This weekend also features Spartan Trail Race.

All finishers receive a T-shirt, medal and professional photos, and every registration comes with access to the Spartan Account to track your tickets, race results, photos, teams, and challenges.
