Half marathons in Texas, 2026-27

36 of the 60 courses list a net drop of zero: the start and finish are at the same elevation on the certificate. They are Energy City Race Half Marathon, Justice Run Fort Worth Half Marathon, DRC Half Marathon, Half CRAZY Half Marathon, Harbor Half Marathon, Toyota Music Factory Half Marathon, Vibha Dallas Dream Mile (Half Marathon), Running the Distance, Running the Distance, Georgetown Half Marathon, BMW Dallas Marathon Half Marathon, Decker Challenge presented by Next Level Urgent Care, Irving Frost Half Marathon, Texas Marathon Half Marathon, Texas Marathon (Half Marathon), McAllen Marathon Scott Crane Run (Half Marathon), Aramco Houston Half Marathon, Too Cold To Hold Half Marathon, Shottenkirk Kia - Fort Bend Half Marathon, Harlingen Marathon 13.1 Half Marathon, Katy Half Marathon & 5K presented by Houston Methodist, San Marcos Half Marathon, Love on the Run Half Marathon, Galveston Marathon Half Marathon, Towne Lake Half Marathon, Wanderlust Half Marathon, Outlaw Half Marathon, Siesta Half Marathon, Fiesta de Mayo Half Marathon, Badass Texas Half Marathon, Too Hot To Handle Half Marathon, Hot Trot Half Marathon, Hope & Healing Place Half Marathon, Sugar Land Half Marathon, 10K & Mile, Citizens Run Against Cancer Half-Marathon and South Texas International Marathon (Half Marathon).

The biggest net drop on the list belongs to Spurs Austin International Half: up to 338 ft (103 m).

Net drop compares only the start and the finish. It says nothing about the hills in between, so a zero-drop course can still climb.

Some Texas half marathons are missing because their certificates have lapsed. On October 11, 2026 the database held no active half marathon certificate for these events; the newest one listed expired in the year shown: Big D Texas Half-Marathon 2016, Dallas (2025); Seabrook Lucky Trails Half Marathon, Seabrook (2025); Miracle Match Half Marathon, Waco (2025); Cypress Half Marathon, Cypress (2025); Army Half Marathon, Temple (2024); The Panhandle Half Marathon, Lubbock (2024). Ask the race whether the current course is certified.

USATF lists 171 active half marathon course certificates in Texas, covering 94 events. We list the races we could confirm, sorted by date, with each course's net drop from start to finish. The 18 certified events we could not tie to a current race are named at the end.

We started from the USATF course certification database: every course in Texas certified at the half marathon distance with an active status, searched on October 11, 2026. We grouped the 171 certificates into 94 events, then opened each race's official website for its name, city and next date. A race is listed only when its official site shows a half marathon in its current or most recent edition. Dates come from the official sites; where a site has not published the next date, the table shows the month of the last edition.

A certified half marathon course is accurately measured, so a time run on it is a true half marathon time. Certification codes and drops are facts from the USATF database (certifiedroadraces.com), which the USATF Road Running Technical Council maintains. Race directors can change courses, so confirm with the race before you build a season around one.
