    CASTAIC LAKE.

    The 35th annual Castaic Lake Triathlon takes place at scenic Castaic Lake just 20 miles north of Los Angeles. The Castaic Lake Recreation Area, located just north of Santa Clarita, is an 11,200-acre multi-use facility with two lakes, boating, world class fishing, hiking, walking, horseback riding, wake boarding, jet-skiing, camping, picnicking, kayaking, and sailing. August is a great time to enjoy the water in the high 60s, and a staging area aptly named Paradise Cove. "Tri-cation" Friday night camping available through Castaic Lake.

    THE COURSE.

    The swim course is a modified V shape in Paradise Cove at Castaic Lake, with 8 lifeguards in the water on paddleboards. The bike course then goes out on back roads to limit your interaction with cars. The bike course does include some U-turns on back roads to allow this, so athletes should slow down at the turn around points. The run is primarily on the rolling trails overlooking Castaic Lake.

    WHO WE SUPPORT

    All proceeds will benefit the Canyon High School Cross Country and Track Teams (we've been doing this for 33 years to support our programs).

    This is a great triathlon for new triathletes. For years our coaches and athletes have encouraged new triathletes (young and old), and created a welcoming atmosphere of support. We offer an enjoyable experience for triathletes of all experience levels.

    AIR TEMPERATURE (AVG).

    Mid June temperatures are often cooler in the morning, with early morning fog burning off to reach the mid 80s. Our event will possibly be around 60 degrees.

    WATER TEMPERATURE (AVG).

    Water temps in June typically range in the mid to high 60s. Email updates will be sent out closer to the race with updates. Use the 20% CALTRI2025 discount code at blueseventy. Note: Fusion wetsuits not eligible for discount.

    This event is a fundraiser for Chingonas on the Run and an opportunity to bring our community together through running and camping.

    [72.png] Chingonas on the Run: Camp & Loop [72.png] [72.png] [72.png]

    Where miles, mountains, and mujeres meet.

    Join us for a weekend that’s more than just miles — it’s a celebration of grit, comunidad, and the kind of campfire connections that linger long after the headlamps switch off.

    On Sunday, June 28, 2026, you’ll take on a 6-hour challenge to complete as many loops as your legs (and ganas) can handle within the 6-hour timeframe. Each loop is 4.16 miles with 728 ft of gain, winding through sweet single track trails in the heart of the Angeles National Forest, summiting Mount Hillyer each time you circle. The loop starts and finishes at basecamp where our aid station will be ready to keep you fueled, hydrated, and cheered on — every lap, every time. Click here to view route.

    Note the cut-off to start the last loop is 11:45 AM. Chingonas have the option to set out for one last loop by 11:45 AM or hang out at basecamp to ring their cowbell to welcome the remaining finishers. As a reminder you are encouraged to run at your own pace and ability. We are here to support you on any goal you set for yourself within the 6-hour time frame.

    [72.png] The Flow

    Saturday, June 27, 2026:

    Camp check-in opens 2:00 PM – 4:00 PM (no late arrivals). Find your spot, pitch your tent, settle in under the pines. Your campground fee is included in your registration, so all you need is your gear and your ganas — and if you don’t have gear, no problem! Email us and we’ll connect you with resources to borrow what you need.

    Sunday, June 28, 2026:

    The loop begins at 7:00 AM, weaving through that sweet single track with your Chingona crew towards Mount Hillyer. Each loop starts and ends at our basecamp aid station, stocked with snacks, hydration, and all the encouragement you need to keep going, loop after loop. Run your heart out until the clock strikes 1:00 PM — see how many summits you can bag before the final bell rings.

    When the loops are done, it’s time for a post-run celebration. Gather for a hearty lunch meal, swap stories, laugh under the pines, and soak up that Chingona magic. You’ll walk away with a finisher’s medal and a keepsake to remember every brave mile and every unstoppable smile.

    Closing ceremony will end at 5:30 PM, runners will be able to clean-up and depart between 5:30 PM - 8:00 PM (Note: Sunset is at 8:07PM).
