Houston Marathon 2027

The Chevron Houston Marathon is a single-loop course starting downtown (Congress Avenue, near the George R. Brown Convention Center). It heads through Washington Avenue, River Oaks, Upper Kirby, Montrose and the Museum District to the Medical Center, loops around Rice University and through West University toward the Galleria, then returns via Tanglewood, Memorial Drive and Allen Parkway into downtown, finishing at Discovery Green. The course is flat and fast with less than 60-75 m of total elevation change; the only notable climb is a highway overpass.
