The Temecula Spartan Race weekend takes place at Lake Elsinore in September, offering Sprint (5K/20 obstacles), Super (10K/25 obstacles), and two endurance formats — the HH12HR (12-hour) and HH4HR (4-hour) — for those who want to go longer. It’s the last SoCal Spartan weekend of the year, making it the final shot at a Trifecta if you’re still chasing one. The venue is a flat, fast course compared to Big Bear, which makes it a solid option for first-timers or anyone going for a PR. Register at spartan.com/en/races/southern-california.
