If you have lived along the western stretch of the coast for more than a year, you already know the sound of a normal September Sunday morning: a car every few seconds on Pacific Coast Highway, a truck downshifting near the Zuma lot, maybe a leaf blower two lots over. Next Sunday, September 20, that sound disappears for a few hours. The highway goes quiet in a way it almost never does, and if you didn't know why, you'd assume something had gone wrong.
Nothing has gone wrong. The Zuma Beach Triathlon returns to Malibu on September 19 and 20, and the version you'll see is smaller, calmer, and more locally run than the event that used to carry the Malibu name. That's not an accident of scheduling. It's the direct result of a fight over who got to run a triathlon on this coastline, and the city chose the option that closed less of your road.
What Actually Closes, and When
The event runs across two days with very different footprints. Saturday is mostly contained to the sand: packet pickup, a kids' triathlon, and a beach expo. Sunday is the day that reaches the highway.
| Day | Time | What's Happening |
|---|---|---|
| Sat, Sept 19 | 6:30 a.m. | Parking opens, packet pickup begins |
| Sat, Sept 19 | 8:00 a.m. | Kids Triathlon starts |
| Sat, Sept 19 | 12:00 p.m. | Beach Expo opens |
| Sun, Sept 20 | 4:30 a.m. | Parking opens |
| Sun, Sept 20 | 6:30 a.m. | Zuma lot gates lock, no exit until after 10:30 a.m. |
| Sun, Sept 20 | 7:00 a.m. | Olympic Distance starts, PCH closes for two laps |
| Sun, Sept 20 | 7:30 a.m. | Zuma Distance starts, PCH closed for one loop |
| Sun, Sept 20 | 10:30 a.m. | Awards ceremony, lots reopen |
The detail worth building your morning around is the 6:30 a.m. lockout. If you park in the Zuma lot Sunday morning to walk the dog or grab a coffee before the roads close, you are committing to staying until after 10:30. There's no early exit built into the plan. If your Sunday requires being somewhere by 9, route around Zuma entirely rather than gambling on a gap in the schedule.
Why It's Called the Zuma Beach Triathlon Now
For years, this race carried the Malibu name. Longtime residents might still call it that out of habit. The rebrand followed a change in who runs it, not a change in what it is, and that change came out of a fight that played out at Malibu City Hall in early 2024.
When the permit for the old Malibu Triathlon expired after its November 2023 edition, the city council didn't simply renew it. They opened the contract to competitive bidding. Four groups submitted proposals, including a global events company called Super League Triathlon, which had run the prior event and wanted to expand it, and the Zuma Foundation, a Malibu-based nonprofit run by Michael Epstein, the triathlon's longtime executive director, who launched the race's Corporate Challenge fundraising format at Zuma Beach back in 1997.
Super League offered a larger donation commitment, roughly $125,000 a year against the Zuma Foundation's $100,000 baseline, and initially proposed keeping their existing two-day commercial format. The council picked the smaller nonprofit anyway. The city's own agenda report explained the reasoning in plain terms: the winning proposals "demonstrated a commitment to minimizing road closures and community impacts." One councilmember involved in the selection noted that every member of the Zuma Foundation's board was a Malibu resident, which mattered to a committee choosing who gets to shut down the highway.
That's the mechanism behind the quiet you'll notice next weekend. The event you're watching is the version the city selected specifically because it asks less of the people who live here, not the version a larger promoter wanted to build.
The Course Itself
The swim starts and ends at Zuma Beach under full Los Angeles County lifeguard coverage. From there, the two adult distances split by ambition. The Zuma Distance is a half-mile swim, a 16-mile bike leg on a single closed loop, and a 4-mile run. The Olympic Distance steps up to a 1.5-kilometer swim, a 40-kilometer bike leg run as two full laps of Pacific Coast Highway, and a 10-kilometer run. Entry for the Olympic field is capped at 500 competitors, which is a small number for a course that closes a state highway.
The organizers describe the closed bike leg as "the safest day of the year to ride Pacific Coast Highway," which is true for the athletes and beside the point for everyone who lives on it. Most days, PCH belongs to cars. For a few hours next Sunday, it belongs to bikes, and the trade only works because the closure window is tight and the course loops rather than sprawls.
The run finishes with a stretch toward the Point Dume cliffs and back, with a timing-chip-verified loop near the point itself. If you're walking the beach that morning, you'll see runners tracking the same headland that anchors most Point Dume real estate listings, just on foot instead of from a bluff-top deck.
Where the Money Actually Goes
The event's Corporate Challenge, presented by Pepperdine University, follows the Zuma Distance course with a fundraising requirement built in: a $250 minimum per participant, with additional perks at $350 and $500. It benefits the Challenged Athletes Foundation, which funds adaptive equipment and competition support for athletes with physical disabilities, some of whom are training toward the LA28 Games.
The broader event also supports the Boys & Girls Club of Malibu, which has expanded well beyond after-school programming since the Palisades Fire. It now runs long-term disaster recovery services, mental health support, and care coordination for affected families alongside its usual youth programs. This year's race is set to donate $55,000 to the Club, up from $50,000 in 2025. Across Epstein's races at this beach over the years, the cumulative fundraising figure has passed $20 million.
None of that shows up when you're stuck behind a cone truck on PCH at 7:15 on a Sunday morning. But it's the reason the closure exists in a form small enough to work around rather than a form that swallows the whole weekend.
The Weekend in Practice
If you live west of Trancas Canyon Road or anywhere along the Zuma frontage, plan next Sunday morning as if the highway simply isn't there between roughly 7 and 10:30. Errands, beach mornings, and anything requiring a drive south toward Pepperdine or north toward Trancas should happen before 6:30 a.m. or wait until after the awards ceremony wraps. Saturday carries almost none of that friction. The kids' race and expo stay contained to the sand and the parking lot, so a normal Saturday on this part of the coast should feel normal.
What's actually worth sitting with is how much smaller this event is than it could have been. A bigger operator wanted this weekend for itself. The city said no, and said so specifically because the alternative asked too much of the highway and too little of the neighborhood. The quiet you'll hear that Sunday morning is not the absence of a decision. It's the result of one.
