Many runners want fast and flat marathons in the spring to qualify for Boston. These 8 spring marathons are fast, flat, and well-organized, setting you up for a PR and BQ.
When it comes to marathons, I don’t want to mess around with a slow marathon course. I want the flattest and fastest marathon course I can find. You’d think that would be easy to come by—but it’s actually not! Especially in the spring. But I’ve done by research to find the fastest U.S. marathons in the spring.
Why I researched the fastest spring marathons
After running the California International Marathon this year, one of the fastest marathon courses in the country with about one-third of runners qualifying for the Boston Marathon, I wanted to keep going on chipping away my marathon time.
I lined up in Folsom, California, after being out of the sport for 2.5 years with injuries, ready to run a sub 2:50 marathon. However, my legs said “not today, Whitney!” and locked up at mile 16 and I ran a 2:58.

After I licked my wounds, I started plotting for the next one. I’m not interested in running famous or pretty marathons at this point. I’m not rushing to sign up for the majors, including the Boston Marathon. While I still can, I want to see how fast a marathon time I can get.
Unfortunately, there aren’t a ton of fast and flat spring marathons in the U.S. Maybe it’s because winter running is grueling?

So, the best marathons are in the fall? And, if you want a shot at running a fast marathon time or nabbing a Boston Qualifier, you need to run your race before June in most parts of the country because otherwise it gets too hot. Your body has to work harder to keep itself cool which slows your running pace. When temps creep above 59 degrees is when this begins to happen.
There are several spring marathons that are fast and flat. I share the fastest and flattest marathons that give you a good shot at a BQ below.
Criteria I looked for to find these fastest marathons included:
- Boston qualifier percentage
- Number of course turns
I don’t want you wasting time on marathons that are poorly organized or have a ton of turns that can add time. I also include spring marathons all over the country because maybe you’re like me, and don’t want to travel too far away from the family.
After CIM, my husband and I were like—yeah, let’s pick a close one that maybe even the kids can come to next time.

Okay, let’s roll!
8 Fastest Marathons in the Spring in the U.S.
1. Woodlands Marathon
Woodlands Marathon Description: Okay, so the Woodlands Marathon is technically in winter, but because it is warm in the heart of Texas, I am including it on the fast Spring Marathons list.
The Woodlands Marathon is the fastest course in Texas, one the top 25th fastest courses in the country, and qualifies close to 11 percent of its registered runners for the Boston Marathon.
The Woodlands marathon course traverses the streets of Town Center and the community on a pretty flat course, finishing on the scenic The Woodlands Waterway. There are several “cheer zones” to keep you motivated.
Past runners say it is a fast and flat course. However, I will say that race distance was miscalculated in one year. So keep that in mind.
- Location: Woodlands, TX
- Date: Feb. 25, 2023
- BQ percentage: 11 percent
- Weather: High is 67 degrees and low is 46 degrees. It rains just 5 days in the month of February on average.
- Course: This course consists of a few loops and does have rolling hills throughout.
- Elevation: Starts at 175 feet and ends at 220 feet. Net elevation gain of 472 feet.Read more about the course here.
- Pros: Fast with great crowd support. Best weather you can find in a fast, flat spring marathon in February!
- Cons: Quite a bit of turns on the course so be sure to run the tangents. Not a huge Boston qualifier marathon compared to some of the others on this list. Also, even though it isn’t that hot most years, it is almost always HUMID.
2. Myrtle Beach Marathon
Myrtle Beach Marathon description: This race runs through the main streets of Myrtle Beach with part of it along the coast itself. Runners like the view of the ocean and the sea breeze. There isn’t a lot of crowd support throughout the race and some said it wasn’t well organized. For example, pedestrians ran in front of some runners and aid stations ran out of fluids later on in the race when the temps climbed into the high 60s.
- Location: Myrtle Beach, SC
- Date: March 4, 2023
- BQ percentage: 12.3 percent
- Weather: High is 65 degrees and the low is 47 degrees. It rains on average 5 days in March. Slight sea breeze.

The course runs from Market Common, all the way up Ocean Boulevard to the Dunes section of Myrtle Beach. Runners will see the Myrtle Beach SkyWheel and Boardwalk, beachfront hotels and Thunderbolt Park.
- Elevation: Starts at 5 feet, maxes at 32 feet with a net gain of 522 feet. See the marathon course details here.

3. Carmel Marathon
Carmel Marathon description: The Carmel Marathon is an extremely well-organized event with a great finisher’s medal, a nice race expo and packet pick-up, and supportive volunteers. The first half of the race is primarily downhill. I would love to run this race again in better weather. The course is scenic running past large homes with beautiful landscaping and plenty of volunteers and spectators. The Carmel Marathon is the 34th largest marathon in the US, with more than 29 percent of runners crossing the finish line as Boston Qualifiers.

4. Colorado Marathon
Colorado Marathon Description: The Colorado Marathon is one of the best marathons to qualify for the Boston Marathon because of our downhill course. The gradual decline in elevation gives runners a fast advantage that not many other Boston qualifier races provide. Between 16 to 18 percent of runners get a BQ. The course is mostly scenic and goes down the Poudre River Canyon in northern Colorado. Read more about the Mountains 2 Beach marathon BQ course here.

5. Mountains 2 Beach Marathon
Mountains 2 Beach Marathon Description: The Mountains 2 Beach Marathon has a loop for the first 7 miles around the picturesque town of Ojai where orange groves are on your right and mountains are on your left. The course then takes you on scenic bike paths. The net downhill is noticeable and may impact some runners’ quads who do not train on downhills.

- Date: May 21, 2023
- BQ percentage: 19.9 percent
- Weather: The average high is 78 degrees and low is 48 degrees. It rains just one day on average in May.

- Pros: Net downhill makes it lightning-fast BQ course, and the course is gorgeous throughout.
- Cons: There was a massive disorganization in 2022 that had many runners warning you to stay away from this race. Also, if you don’t train on downhills, it could rip up your quads.

Grandma’s Marathon Description: The Grandma’s Marathon is one of the most popular destination marathons because of its speed, scenery, and organization.

- Pros: Well organized, scenic, supported, and lightning fast.
- Cons: Duluth can be hard to get to! Overall, I did not find any complaints about the organization.
(Honorable Mention Fast Marathon) Oak Ridge to Kingston Express Marathon
Oak Ridge to Kingston Marathon description: I am including this local (to me) race for those who only care about a FAST MARATHON TIME. This no-frills race is primarily targeted to those seeking a Boston Marathon qualifying time or half marathon performance indicator. You are encouraged to only participate if you think you will meet the Boston Marathon qualifying standards. The participant cap is only fifty people! But 85 percent of those runners qualify for Boston on this flat (for East Tennessee) out-and-back course.
- Location: Oak Ridge, TN near Knoxville
- Date: March 5, 2023
- BQ percentage: 85 percent
- Weather: High is 63 degrees and the low is 40 degrees. It rains on average 10 days in March.
- Course: The course is an out-and-back on the Oak Ridge Turnpike with bike lane/shoulder. View a race recap here.
- Elevation: Max gain of 600 feet. It starts with a net downhill and has rollers in the middle. Because it is an out-and-back, what comes up must come down–and vice versa.
- Pros: This race has no turns, just curves in the road, and is relatively flat. Weather is almost always cool.
- Cons: This is a no-frills race with little to no crowd support and runners around you. This race is for those meaning business when it comes to BQ. I recommend having a friend pace you for some of the back half of this race and making sure family and friends are there to cheer.
