Why California is both the best and the trickiest state to pick a marathon in
Nowhere else in the country can you choose between a net-downhill December BQ machine, a coastal February first-timer, a wine-country spring race, and one of the most photographed courses on earth, all within a single state. That abundance is the problem. Runners pick a California race for the wrong reason all the time: they sign up for Big Sur chasing a PR, or they enter LA because it is famous. This post is the correction.
Four goals. Four honest picks. One important caveat each. Skip the races that do not fit your goal, including LA (1% BQ rate, rolling course, 21,933 runners) and San Francisco (3% BQ rate, genuinely hilly). Both are fine experiences. Neither is on this list, because this list is about matching the race to what you actually need.
Best California marathon for a BQ: California International Marathon
The answer is CIM, and it is not close. No other California race comes within 8 percentage points of its BQ rate. Three things stack in your favor on race day: the December air stays cool, the point-to-point course drops 350 feet from Folsom to Sacramento, and the field self-selects for serious runners. A strong pacer program does the rest.
That 350 feet of net drop is free speed, until your quads file a complaint at mile 20 if you went out too hard. Respect the downhill early and it pays you back late.
The honest caveat: a December race means your peak training block runs straight through summer heat. Build that into your plan. Registration also fills quickly, so if you are reading this in July, check availability now. CIM sits squarely in The Best Boston Qualifier Marathons collection for a reason.
Best California marathon for a PR: Mountains 2 Beach
If your goal is a raw PR, not necessarily a first BQ, Mountains 2 Beach is worth a serious look. The race runs point-to-point from Ojai down to Ventura Beach. The course is cataloged as flat, the May morning temperatures are manageable at a high of 68 degrees, and the 22% BQ rate tells you the field runs fast.
The trade-off is real: M2B's downhill is more aggressive than CIM's. That can shave meaningful time off your finish if you have done downhill-specific training. If you have not, you will feel it in your quads from mile 20 onward, and any time you banked early will bleed away. CIM is the safer route for a first BQ attempt. M2B rewards runners who have done the preparation to exploit a fast downhill without blowing up.
The spring option worth flagging: Napa Valley Marathon. It runs in March, carries a 13% BQ rate, sits at a field of 1,942, and drops 303 feet over a mostly flat point-to-point course through the valley. Cooler March temps are a genuine advantage. It will not beat CIM or M2B on raw pace potential, but it is the most underrated spring BQ window in California. All three belong on The Best Net-Downhill Marathons list.
Best California marathon for a first-timer: Surf City or Long Beach
First marathons are about getting to the finish line healthy and wanting to do it again. You need a flat course, manageable weather, and enough crowd energy to carry you through mile 20 when the wheels threaten to come off.
Surf City in Huntington Beach is the cleaner pick for a first-timer who wants to control as many variables as possible. February means cool coastal air, a high of 67 degrees, and a flat course that does not ask anything complicated of you. The field of 1,963 is small enough that it never feels overwhelming. It is not a BQ race, and it is not trying to be. It is a well-organized race on a forgiving course at the right time of year.
Long Beach offers a larger field of 4,722 and more festival energy, which some first-timers need to stay motivated through the back half. The course is flat. The crowd is loud. But the October date is the honest flag: a high of 79 degrees is a real wildcard on race day. Heat is the single biggest risk factor for a first marathon going sideways. If you are heat-sensitive or training somewhere that makes heat acclimatization difficult, take that seriously.
OC Marathon in Costa Mesa is a solid Southern California alternative. Flat course, field of 3,618, high of 70 degrees. If the Long Beach date makes you nervous and you want something between Surf City's intimacy and Long Beach's energy, OC is worth a look.
Best California marathon for scenery: Big Sur (with an honest warning)
Big Sur is the most photographed course in American marathon running. You run Highway 1 along ocean cliffs, through redwood shadows, past the Bixby Bridge with a tuxedoed pianist playing in the wind. It is a genuine experience. It is not a time race.
The course is hilly. The 10% BQ rate sounds reasonable until you realize it reflects only the most experienced runners in a field that self-selects for bucket-list motivation. Expect 10 to 20 minutes slower than your flat-course PR. The 300-foot net drop does not make up for the climbs in between. If you are chasing a BQ or a PR, this is the wrong race. If you are an experienced runner who already has a qualifier and wants to run something memorable, this is exactly right.
Runner-up for scenery: Avenue of the Giants Marathon in Weott. You run under old-growth redwood canopy for most of the race. The field is small, just 396 runners, the course is mostly flat, and the high of 56 degrees is excellent. The 5% BQ rate is low, but the course is genuinely fast enough to PR on for the right runner. If you want beauty without Big Sur's hills and drama, Avenue of the Giants is the quieter, more honest version of the same impulse.
Small field. Cool temps. Redwood canopy from start to finish. Worth knowing about.
The California race nobody talks about: Santa Rosa
Santa Rosa has a 16% BQ rate, second only to CIM among California races. The field is 1,349, which means you get a serious, competitive environment without CIM's registration pressure. The course is mostly flat. The wine country setting is genuinely pretty.
Here is the fact that almost nobody mentions: Santa Rosa's race-day high of 82 degrees is the warmest among California's serious BQ options. That heat will cost you time and raise your risk of a bad day. Every other review of this race leads with the BQ rate and buries the temperature, or skips it entirely. We are not doing that.
Who Santa Rosa is actually for: a runner who missed CIM registration, wants a smaller-field BQ attempt, and is heat-acclimated or willing to race conservatively and protect themselves in the back half. It is a legitimate option. Go in with your eyes open about the conditions.
How to pick your California race
Here is the honest one-page version.
A few races that did not make the list: LA Marathon has 21,933 runners, a rolling course, and a 1% BQ rate. San Francisco is hilly with a 3% BQ rate. Rock n Roll San Diego carries a 2% BQ rate on a mostly flat course. They are fine events. They are not the right answer for any goal on this list, and pretending otherwise would waste your training block.
If you want to go deeper on course data, the Best Marathons in California collection has the full state picture. The Best Net-Downhill Marathons and The Best Boston Qualifier Marathons collections show how California's top picks compare nationally. And if you want to understand exactly how BQ-friendliness gets scored, I Scored 200 Marathons for BQ-Friendliness. Here's the Method. is the place to start. The Best West Coast Marathons and The Flattest, Fastest Marathons collections are also worth a look if your search extends beyond California's borders.
Still not sure? The quiz takes about two minutes and matches your goal, timeline, and preferences to the specific race that fits.
