Every upcoming Half Marathon around Houston, with start times, entry fees, finish-time stats from past editions, start-line maps, and the local run clubs to train with.
43 upcoming half marathons found · 10 with finish-time stats
Houston racing is shaped by the same bayous and park loops that define daily training here. The course under your feet on race day is likely the same greenway, crushed gravel, or bayou-side path you already know from morning runs along Buffalo Bayou, through Memorial Park, or around the Rice University loop - familiar ground, which takes a lot of the guesswork out of pacing.
Summer races here are a genuine test of heat tolerance, and locals know it. The racing calendar spreads across all four seasons, so you can pick your weather window, whether that means a cool fall morning in October or a dawn start in August when the humidity is already doing its thing before the sun clears the skyline.

Common Questions About Running a Half Marathon in Houston
How big are the fields at Houston half marathons?
Field sizes vary. The Red, White and Blue Half Marathon - Houston, for example, had a published field of 169 finishers - a size where you will not be lost in a crowd but you will not be racing alone either. Most races here have not published field-size data, so that single figure is the clearest read we have on what a smaller Houston half marathon actually feels like on the ground.
What can I expect for a finish time?
Only 3 of the 35 half marathons here have published finish results. The Red, White and Blue Half Marathon - Houston shows a median finish time of 2:31:05 across its published results - a useful anchor if you want a rough sense of where the middle of a Houston half marathon field lands. The other 32 races have not published results, so we cannot speak to their fields.
When is the best time of year to race a half marathon in Houston?
Fall is the busiest stretch, with 17 races running September through November and October alone hosting 7. If summer heat is not your thing, fall gives you the most options in cooler conditions. Winter still offers 10 races from December through February, and the mild Gulf Coast climate means outdoor racing is realistic all year.
Do Houston half marathons give out shirts or medals?
34 of the 35 races say they give a shirt. None of the races here say they give a medal - though 1 race has published no giveaway details at all, so that one race simply has not said either way.
