What Are the Popular US Marathons? Big Sur, Houston & More

Popular US marathons attract runners for different reasons. Some are known for their scenery, some for their size and history, and others for course characteristics that are relevant to specific race goals. The right race can depend on much more than the 26.2-mile distance.

If you’ve ever scanned a race calendar and wondered why one marathon stands out for its scenery while another is known for its course profile, the differences often come down to course design, timing, location, entry, and event scale. Across the United States, well-known marathons can offer very different race-day experiences.

What Makes a Marathon “Iconic” in the US

A marathon’s reputation can be shaped by several factors, including size, setting, history, and access.

Size affects the practical side of race day. A large field can involve multiple corrals, extensive start and finish logistics, and a large spectator presence. Setting also contributes to a race’s identity, whether the course runs along a coastal highway, through a city surrounded by landmarks, or through a major downtown area.

History gives some marathons a long-standing place in the sport. Races with decades of tradition, recognizable names, and established course routes can attract runners from across the country and around the world. Access is another factor. Different races may use open registration, lottery-based entry, charity programs, qualifying standards, or a combination of entry paths.

These differences give runners several practical factors to compare, including scenery, course profile, race date, location, entry method, and event logistics.

Profiles of the Most Popular US Marathons

Big Sur International Marathon: Scenic and Challenging

The Big Sur International Marathon is a point-to-point race that runs along scenic California Highway 1 from Big Sur to Carmel. The course features redwoods, coastal views, mountains, and pastures, with Bixby Bridge located around the halfway point. The race is held on the last Sunday of April.

The course is officially described as moderately difficult, with rolling hills. It is USATF certified, AIMS/World Athletics certified, and its times can be used for Boston Marathon qualifying.

The course profile is an important consideration when planning your race. Its rolling terrain and point-to-point layout create a different course profile from a relatively flat city marathon. Coastal weather can also vary, so race-day conditions are another factor to monitor.

The Bixby Bridge section is one of the race’s defining landmarks. The official course description also highlights the piano performance at the bridge, where a concert pianist plays during the marathon.

For runners considering Big Sur, the combination of coastal scenery, rolling terrain, spring timing, and destination-race logistics provides several factors to consider when planning.

Marine Corps Marathon: The People’s Marathon

The Marine Corps Marathon is a marathon that starts and finishes in Arlington, Virginia, with the course entering Washington, D.C. before returning to Arlington. The event is officially known as “The People’s Marathon” and features landmarks across the National Capital Region.

The course passes through areas associated with Arlington and Washington, D.C., including sections near the National Mall and other major landmarks. Race operations also involve transportation and event logistics across the region.

The marathon does not offer prize money. According to the 2025 official media guide, 40,000 runners registered for the 50th running, making it the largest field in the event’s history at that time. The same guide described the MCM as the largest marathon without prize money and among the largest marathons in the United States and the world.

For a large event spread across Arlington and Washington, D.C., transportation, corral assignments, and arrival timing are important parts of race-day planning. The event’s travel guidance also provides information on Metro access before race morning.

Houston Marathon: Flat Course and Winter Timing

The Houston Marathon is a winter marathon held in Houston, Texas. The official race site describes its course as “flat and fast” and identifies it as a Boston qualifier course.

The flat course profile is one objective characteristic to consider when comparing races. It differs from the rolling terrain of a race such as Big Sur, although a flat course does not remove the demands of the marathon distance.

Houston’s January timing is another factor. The 2027 Chevron Houston Marathon is scheduled for January 17, 2027. Race-day weather can still vary, so runners planning a winter marathon should consider the conditions expected for the specific race year.

The 2027 registration period ran from January 11 through January 26, 2026, according to the official registration information. That registration window has already closed. Future registration dates and availability should be checked on the official race site rather than carried forward from the 2027 schedule.

Other Popular US Marathons Worth Knowing

Chicago, New York City, and Boston provide useful reference points when looking at the broader US marathon landscape.

• Chicago Marathon — A major-city race with a flat and fast course that starts and finishes in Grant Park and runs through 29 Chicago neighborhoods. It is part of the Abbott World Marathon Majors.

• New York City Marathon — A major-city marathon that runs through all five boroughs of New York City: Staten Island, Brooklyn, Queens, the Bronx, and Manhattan. It is also part of the Abbott World Marathon Majors.

• Boston Marathon — A historic marathon with qualifying standards for the main field, along with other entry opportunities such as official charity programs. Meeting a qualifying standard does not guarantee entry because the field is limited and applications may exceed available places.

For the 2027 Boston Marathon, the B.A.A. introduced new procedures for qualifying times from courses with significant net downhill. Verified qualifying times from courses with a net drop of 1,500 to 2,999 feet receive a five-minute adjustment; courses with a 3,000- to 5,999-foot net drop receive a 10-minute adjustment; and courses with a net drop of 6,000 feet or more are not accepted for Boston qualifying purposes. These procedures apply to qualifying results submitted for the 2027 Boston Marathon registration process.

These races illustrate how different factors can shape a marathon’s identity, from course profile and city setting to history and entry requirements.

Entry, Timing, and Logistics: How to Actually Get In

Getting into a major marathon depends on the specific event. Entry systems can include open registration, qualifying standards, lotteries, charity programs, or other registration paths, and these options can change from year to year.

For the races covered here, the general planning picture looks like this:

• Big Sur International Marathon — Typically held in April, with the course running from Big Sur to Carmel. The official site currently lists the race on the last Sunday of April.

• Marine Corps Marathon — Typically held in October in Arlington, Virginia, and Washington, D.C. The 2026 marathon is scheduled for October 25, with registration information published by the official event.

• Houston Marathon — Held in January, with the 2027 race scheduled for January 17. The 2027 registration period ran from January 11 through January 26, 2026, and is no longer open.

Boston requires a different type of planning. For the 2027 race, runners who achieved a valid qualifying time could apply during the B.A.A.’s September 2026 registration period, but achieving the qualifying standard alone did not guarantee a place in the field.

Registration is only one part of planning. Once you have an entry, look at packet pickup, transportation, start-line access, and the location of your accommodation. Point-to-point races can require additional transportation planning, while major-city events may have multiple access points and extensive road closures.

Race-week schedules can also vary. Checking the official event site before booking travel or finalizing your training calendar helps ensure that you are working from the current dates, entry rules, and race-day instructions.

Course Difficulty, Weather, and Atmosphere Compared

The three featured races differ in several objective ways.

Big Sur is a point-to-point marathon with rolling hills and a coastal setting. It takes place in spring, and the official course description classifies it as moderately difficult. Coastal conditions can vary, so weather is another factor to consider when preparing for the race.

Marine Corps takes place between Arlington, Virginia, and Washington, D.C., with a landmark-focused course and a large field. Its fall timing and event operations make transportation, start access, and race-day logistics important parts of planning.

Houston takes place in winter and uses a relatively flat course through Houston. The race is also identified by the event as a Boston qualifier, meaning eligible results can be used toward Boston Marathon qualifying under the B.A.A.’s rules.

Weather adds another variable to all three. Coastal races can experience changing conditions, fall races in the Mid-Atlantic can vary from year to year, and winter races in Texas can also see different temperatures and conditions on race day. Checking the forecast closer to the event is more useful than relying on a general expectation for the season.

How to Choose the Right Marathon for You

The most useful way to compare US marathons is to start with your own priorities and then look at the characteristics of each race.

• If course scenery is a major priority, Big Sur offers a coastal point-to-point route, rolling hills, and a Highway 1 setting.

• If you are interested in a large race connected with Arlington and Washington, D.C. landmarks, the Marine Corps Marathon offers that setting along with a fall race date and extensive event logistics.

• If a relatively flat course and winter timing matter for your race planning, Houston provides those characteristics. Its official course information also identifies the event as a Boston qualifier.

Entry method, course profile, race season, travel requirements, and your own training can all be part of the decision. A race that fits one training cycle may not fit another, especially when your goals or schedule change.

Your gear can be considered in the same way. Some runners consider open-ear headphones when they want to listen to audio without covering the ear canal. Open-ear designs leave the ear open rather than sealing it with an ear tip, which can help runners stay aware of their surroundings while listening. The Shokz OpenRun Pro 2 uses an open-ear design and offers up to 12 hours of battery life for longer listening sessions on the run.

Whether headphones are permitted depends on the rules of the specific race. Always check the current event guidelines before race day rather than assuming the same policy applies across different marathons.

The right race depends on the combination of course, timing, entry, travel, and personal goals that matter most to you. Looking at those factors side by side can make it easier to narrow down the US marathons that fit your plans.
