Houston: sold out, with charity entries left
General registration for the Chevron Houston Marathon and Aramco Houston Half Marathon sold out in early August. ABC13 reported it as the fastest sell-out since the pandemic, with about 40,000 participants expected over race weekend, January 13–17, 2027, the most organizers have ever had. The races start downtown on Sunday, January 17. Our Houston half marathon guide has the half’s schedule, cutoffs and pace groups.
The remaining way in is the Run for a Reason charity program (or see where to run instead). ABC13 reports it requires a reduced entry fee plus a $350 donation to one of 68 charities. Some charities have already sold out their spots. Can’t get in? Look at other Houston races: the Run Houston! Race Series and the rest of the Houston & Gulf Coast calendar have open races through the winter.
Dallas: December 11–13, now sold out
The 55th BMW Dallas Marathon weekend starts with a Friday Night Lights mile on December 11. The 10K and 5K are Saturday, December 12. The marathon, half, ultra and relay start at 8:00 a.m. on Sunday, December 13. The race said in April that fees “will increase incrementally as runner registrations increase,” Update, September 27: the marathon, half, 50K, relay and weekend series now show as sold out. The only Sunday entry left is a $500 Legacy Runner fundraising spot. Registration is on Race Roster, not RunSignup, so it doesn’t appear on our calendar. Our Dallas Marathon 2026 guide covers what’s left, the schedule, cutoffs and North Texas alternatives. For other December races in North Texas, see the Dallas–Fort Worth race calendar.
San Antonio: year two of the city’s own marathon
The San Antonio Marathon, run by San Antonio Sports with the city, is in its second year. The 5K is Friday, December 4. The marathon and half start Sunday, December 6. RunSignup shows the final price tier in effect now: $199 for the marathon, $169 for the half and $69 for the 5K, before processing fees. There are no transfers or deferrals. Our San Antonio Marathon guide covers the course, cutoffs and expo. More races nearby are on the San Antonio & South Texas calendar.
Austin: a renamed January half, then the February marathon
The former 3M Half is now the Spurs Austin International Half. It runs Sunday, January 17, 2027 on the same net-downhill course that finishes downtown, which puts it on the same morning as Houston. The launch price was $99 through May 19; prices have gone up since.
The Austin Marathon, half and 5K are Sunday, February 14, 2027, with a 7 a.m. start downtown and the finish on Congress Avenue in front of the Capitol. The race is honoring military service members this year: active-duty and retired U.S. military runners can apply for 50% off any distance, capped at 500 runners, with proof of service. Approvals go out weekly on Thursdays until the spots are gone, and approved runners get a code by email (apply here). Eight weeks later, Austin hosts the 50th Cap10K on April 11, 2027. Our Austin Marathon 2027 guide has current prices, wave times, cutoffs and the half’s course. Other races are on the Austin & Hill Country calendar.
Cowtown: February 27–28, and a transfer deadline to know
Fort Worth’s Cowtown puts the 5K and 10K on Saturday, February 27, and the half, full and 50K ultra on Sunday, February 28. The race says its full and ultra are Boston Marathon qualifiers. Know the fine print: Cowtown has what it calls a 49-year policy of no refunds or deferrals. Transfers to another runner or distance are free until December 31, then cost $30. Online registration closes February 26 at 11:59 p.m. unless a distance fills first. Our Cowtown 2027 guide has the price tiers, course and cutoffs.
El Paso: the same Sunday as Cowtown, finishing downtown again
The Michelob Ultra El Paso Marathon, half and 5K are Sunday, February 28, 2027. For 2027 the race returns to a downtown finish, as at its first edition in 2007, which the organizer says gives runners a net decline. The marathon is a Boston qualifier. RunSignup shows $125 for the marathon and $105 for the half until November 1, when the marathon rises to $130. There are no refunds, rollovers or transfers, and no race-day packet pickup. Our El Paso races guide has start times, the course cutoff and the city’s other races, including the Transmountain Half on November 8 (see our Nov. 7–8 race weekend guide).
Which one should you pick?
- Chasing a Boston qualifier: read our Boston 2027 cutoff explainer first, then pick a cool-weather race and confirm its course is USATF-certified.
- First marathon: San Antonio in December gives you about ten weeks from now to train. Our run-walk guide explains a strategy many first-timers use.
- Chasing a New York qualifier: a December marathon falls inside the window for a 2027 NYC Marathon time-qualifier entry, which closes Dec. 31, 2026, if the course is certified.
- Half instead of full: compare every option on the Texas half marathon calendar.
