USATF Half Champs occasionally. Flat. Cool January.
The Aramco Houston Half is a half marathon held in Houston, TX on January 17, 2027. With a Green Score of 9/10, it's one of the easier, more beginner-friendly US races. The course is flat (~6 ft of gain per mile). Typical race-day weather is a cool 50°F, dew point ~40°F (10-year normal). Entry is around $155. Marathon Compass rates every race across terrain, climate, logistics, travel, and field size so you can find the one that fits you — and build a training plan tuned to your fitness.
Typical start-line conditions (30-year normal (NOAA 1991–2020)): 50°F with a dew point of 40°F. On the temperature-plus-dew-point scale used by our pace engine, that's 90 — a 0% pace penalty. Heat should not be a factor at the Aramco Houston Half in a typical year — race your fitness.
Method: temp°F + dew°F lookup from the heat-adjustment chart our training plans use daily. Sign in to see this adjustment applied to your own projected finish.
First marathons cost more than the entry fee — budget the whole weekend before you commit.
Entry is by lottery with roughly 55% historical acceptance — plan like you might not get in.
Plan B: if entry doesn't go your way, Publix Gasparilla Half Marathon (February 21, 2027, open entry, Green Score 9.1) or Life Time Miami Half (January 31, 2027, open entry, Green Score 8.9) keeps the same training block on schedule.
Stay within walking distance of the start corrals — a 6am rideshare on race morning is a gamble. Book a refundable rate now and forget about it; inventory tightens in the final month. The links below are pre-filled for race weekend (January 15, 2027 → January 18, 2027).
