Every fall, a stretch of Cliff Haven gives up its curbs to runners instead of cars. Signal Road empties out. Kings Road fills with strollers, dogs on leashes, and kids in race bibs three sizes too big. For one Saturday morning, the neighborhood does at scale what it already does every other day of the year in miniature: it puts people on the pavement where cars usually go.
The event is the Harbor Heritage Run, a fundraiser organized by the Newport Harbor High School PTA that has used these streets since 1987. Its 25th running took place on October 29, 2011. Registration listings currently show the run returning in mid-October 2026, though school PTA races have a habit of shifting by a week or two as logistics firm up, so anyone planning around it should confirm the exact date closer to fall.
A Course That Predates the City's Interest in It
Newport Harbor High School sits at 600 Irvine Avenue, inside the same residential grid that includes Cliff Haven. The school opened in 1930 and is now the largest of the four public high schools in the Newport-Mesa Unified School District. The Heritage Run's course loops out from campus and through the surrounding blocks, which is why Cliff Haven has functioned as the race's de facto host neighborhood for decades rather than a passive backdrop to it.
That distinction matters. The Heritage Run began as a school fundraiser and has grown up alongside the neighborhood it runs through. Its 5K, 2K, and kids' race all take their shape from the blocks around the school and the low-speed streets of Cliff Haven.
The neighborhood's core streets, St. Andrews Road, Pirate Road, Snug Harbor Road, Signal Road, Kings Road, St. James Road, and St. James Place, form a tight grid bounded by Irvine Avenue, Dover Drive, 16th Street, and Pacific Coast Highway. None of them were built as thoroughfares. All of them show up, at one point or another, in accounts of where the race passes.
Streets Already Built For This
Cliff Haven doesn't have sidewalks. That's not a maintenance gap. It's a design leftover from a neighborhood built in the late 1940s and early 1950s, before sidewalks were standard on residential streets this close to a school zone. Speed limits stayed low because of the schools nearby, and residents walk in the road as a matter of course, not as a workaround.
That habit is also why coyotes get spotted crossing at Cliff and Signal often enough that neighbors post warnings about it. The streets run quiet enough, most days, that wildlife treats them as open ground. A race that turns those same streets over to a few hundred runners for a few hours isn't asking the neighborhood to become something it isn't. It's asking it to be louder, for one morning, at the version of itself it already is the rest of the year.
Compare that to what doesn't happen. Pacific Coast Highway runs along Cliff Haven's south side and carries real congestion during commute hours. The race doesn't touch it. Neither does it reach into the busier commercial stretch of Mariner's Mile below the bluff. The course stays inside the residential grid, on streets already built for foot traffic and low speeds, which helps explain how a parent-organized PTA event has stayed a fixture of the fall calendar for close to four decades.
What the Morning Actually Looks Like
The event has historically opened early. In past years, race-day registration began around 6:30 in the morning, with an aerobic warm-up around 7:30 before the run itself got underway. The morning has included three separate distances: a competitive 5K, a more casual 2K fun run and walk, and a kids' race for the youngest participants, giving the event a shape that works whether you're training for a time or pushing a jogging stroller.
Food trucks have been part of the tradition too, parked near the school through midday, with a cut of each purchase going back to the PTA. In 2012, that was structured as 20 percent of food truck sales returning to fund PTA programs. The exact vendor lineup and percentage may shift year to year, but the model of tying breakfast sales to school fundraising has stuck around.
The race has not run uninterrupted. The 2017 Harbor Heritage Run was postponed, according to the school's own PTA page, breaking what had otherwise been a steady annual cadence stretching back to 1987. It's a small wrinkle, but a useful one. This isn't an automatic event that happens whether anyone shows up to organize it. It runs because volunteers keep rebuilding it every year, and in at least one year, they couldn't.
What This Means If Signal Road Is Your Street
If you live along the course, the practical version of all this is simple. One Saturday morning each October, expect:
- Reduced or no car access on Signal Road, Kings Road, and the streets immediately surrounding Newport Harbor High School for a few hours in the morning
- Registration and warm-up activity clustering near the school starting around dawn
- Food trucks and foot traffic lingering into midday
- A noticeably different soundscape than the coyote-quiet mornings the rest of the year brings
None of this requires advance planning beyond knowing it's coming. But knowing it's coming is the part that outsiders googling the neighborhood never find, because it isn't documented anywhere except in old PTA schedules and the memories of people who've lived here through enough Octobers to expect it.
That's the version of local knowledge that actually holds up: not a listing description of tree-lined streets, but the specific morning when those same streets fill with runners because a high school PTA decided, back in 1987, that this neighborhood's low-speed, sidewalk-free grid was exactly the kind of course a fundraiser could use.
