Bayou City Summer Run - Houston

Bayou City Summer Run - Houston takes place on July 24, 2027, through the streets of Houston, Texas. Three distances are offered — the half marathon (13.1 mi), a 10K (6.2 mi) and a 5K (3.1 mi) — with children's races alongside. Start times are not listed in our records.

Houston in late July is the hardest place in the country to race a half marathon: the humidity stops sweat evaporating, so your body loses its main cooling mechanism just when it needs it most. Halve your ambitions, drink at every opportunity, and treat any sign of chills or goosebumps as an instruction to stop — in these conditions that is heat illness, not a second wind.
