Houston and San Antonio both state that their courses are USATF-certified, and San Antonio calls itself an official Boston qualifier. Cowtown says its full marathon qualifies too. A time only counts on a certified course, so confirm on the race site, then read our Boston 2027 cutoff explainer.
Houston's course is USATF-certified and draws a huge field, but general entry has sold out, so the practical options are charity entries or another certified course such as San Antonio. Galveston's RunSignup listing describes a flat, fast course along the Seawall on Feb. 21, 2027. Course maps and elevation charts are on each race's official site; compare them before you commit. The Houston sold-out alternatives list has other choices.
San Antonio's 7-hour time limit is the most generous of the big Texas races listed here, and its December date lands in the cool season. Pair it with our run-walk guide, or build up with a Texas half marathon first.
Austin starts downtown at 7 a.m. and finishes on Congress Avenue in front of the Capitol. Prefer dirt? Filter the calendar above to Trail, or see trail races in Texas.
Heat and humidity decide more Texas race days than hills do. Most marathons are scheduled from fall through spring for that reason, but a warm morning in November or March can still arrive, so check the forecast for the host city and start time.
If you train through a Texas summer, do your long runs at dawn, slow your easy pace and let heart rate guide effort. Our Zone 2 heat guide and Texas running tips cover it. On race day, start conservatively and take fluids early. Gear matters too: see our racing shoe comparison and Texas running stores for a fitting.
Texas marathons follow the weather. Here is how the 49 upcoming races spread across the calendar.
20 marathons on the calendar. Fall is when first-timers who trained through the summer cash in, and when the state's late-year road marathons and trail festivals line up almost every weekend.
28 marathons on the calendar. Cool mornings make this the prime window for a fast road 26.2, and the Hill Country trail season stays busy into spring.
Only 1 marathon: Austin Solstice Circuit 52 Miler • 50K • Marathon • 27K • Half-Marathon • 10K • 5K • 12-Hour Solo & Relay (Jul 17, 2027, Spicewood). Texas heat keeps almost every 26.2 out of the summer months, so plan a summer marathon around an early start and plenty of fluids.
Road races built around the full 26.2, in date order. Summaries come from each organizer's RunSignup listing; open a race for events, fees and start times.

Choose a Texas marathon by matching the date and course to your goal. Pick a cooler-season race from late fall to early spring, check whether the course is flat or hilly, confirm the field size and cutoff times, and allow at least 16 weeks of training before race day.
Road or trail. 33 of the upcoming marathons are road or mixed-surface races and 16 are on trails. Trail marathons in the Hill Country run over rock and climbs, so expect a finish time well slower than your road marathon pace. Use the Road and Trail filters above to narrow the calendar.
Time of year. Texas weather does more to your finish time than almost anything else. For a goal race, pick a date between late fall and early spring, and check the historical weather for the host city on race morning. For summer build-up, see our training tips for Texas runners.
Course certification. If you're chasing a Boston qualifier, confirm on the race's own website that the course is USATF-certified before you register. We don't track certification, so check the race's official page.
Who's coming with you. 45 of these marathons also offer a half marathon and many add a 10K or 5K, so friends and family can race the same morning. Still building up to 26.2? Start with one of the half marathons in Texas, use one of the 10Ks in Texas as a tune-up, or bring the family to one of the 5Ks in Texas. 25 put on an ultra distance too, if you're already eyeing the next step: see every ultramarathon in Texas.
Registration window. 47 of 49 have registration open today. Price tiers usually rise closer to race day; each race page shows the current RunSignup fee and when it changes.
Texas has 49 upcoming marathons on the calendar between November 2026 and October 2027, in 31 cities across the state. That count includes every race with a 26.2-mile event listed on RunSignup, from big-city road marathons to Hill Country trail races and relay-only marathons. 47 of them have registration open right now.
Texas marathon season runs from fall through spring. 20 marathons are scheduled September through December and 28 January through May. The busiest months on the current calendar are December 2026 (11), February 2027 (8) and March 2027 (7).
Very few. Only 1 marathon is on the calendar for June through August: Austin Solstice Circuit 52 Miler • 50K • Marathon • 27K • Half-Marathon • 10K • 5K • 12-Hour Solo & Relay (Jul 17, 2027, Spicewood). Texas summer heat pushes almost every 26.2 into the cooler months.
Austin & Hill Country leads with 16 upcoming marathons, followed by Dallas–Fort Worth (11), Houston & Gulf Coast (9) and Central Texas (Waco, Bryan–College Station) (3).
It depends on the goal. For a Boston qualifier, Houston and San Antonio say their courses are USATF-certified and Cowtown says its full marathon qualifies. For a flat, fast course, Houston (sold out for 2027) or Galveston, whose listing describes a flat Seawall course on Feb. 21, 2027. For a first marathon, San Antonio’s 7-hour limit is the most generous of the big races, and Austin finishes on Congress Avenue in front of the Capitol. The best Texas marathons by goal section above compares them.
Houston and San Antonio say their courses are USATF-certified, and Cowtown says its full marathon is a Boston qualifier. Always confirm certification on the race’s own site before you register, because a course must be certified for the time to count.
Yes. 16 of the 49 upcoming Texas marathons are trail races, and 25 of all listed marathons also include an ultra distance in the same event.
