Chevron Houston Marathon

Houston, TX · Sun, January 17, 2027 · 07:01 start

The verdict

Prime BQ course.

Forgiving to run · some friction to enter and reach.

StartMile 7Mile 13Mile 20Finish

Among the flattest US marathons. A few highway overpass bumps. Often called a fast PR course.

Built from this course's named climbs at their real mile markers; between them the line is interpolated, and the descent is placed using the course's curated shape classification rather than measured. It shows where the hard parts fall and how big they are, and it reproduces the real net change end to end — but it is not a GPX trace.

What the Chevron Houston Marathon really costs

A first marathon costs more than the entry fee — budget the whole weekend before you commit.

What the heat costs you at the Chevron Houston Marathon

A typical race morning here scores 86 on the temperature-plus-dew-point scale our pace engine runs daily (47°F + 39°F, 10-year history (Open-Meteo)) — a 0% pace penalty. Heat should not be a factor at the Chevron Houston Marathon in a typical year — race your fitness.

Boston qualification status

Penalty-free Boston qualifierPenalty-free

Net descent of ~3 ft is well under the BAA's 1,500 ft adjustment threshold. Your clock time is your application time.

Computed under the BAA's downhill rules for the 2027 qualifying window (announced Sept 2025; verified July 2026): net start-to-finish descent of 1,500–2,999 ft adds 5:00, 3,000–5,999 ft adds 10:00, and 6,000 ft or more is not accepted. Net descent here is derived from our course elevation data — the BAA's official course designation controls. Sign in to see your projected finish graded against your age-group standard and the realistic acceptance cutoff.

Entry strategy

Entry is by lottery with roughly 55% historical acceptance — plan like you might not get in.

  1. Lottery entry deadlineJune 15, 2026
  2. Registration closesJune 15, 2026
  3. Lottery results announcedJuly 1, 2026
  4. Race dayJanuary 17, 2027

Plan B: if entry doesn't go your way, Shamrock Marathon Virginia Beach (March 21, 2027, open entry, Green Score 9.2) or Ameris Bank Jacksonville Marathon (December 12, 2026, open entry, Green Score 9.2) keeps the same training block on schedule.

Where to stay

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).

Some hotel and book links may earn us a commission, at no extra cost to you. Official registration is never an affiliate.
