Marathon de Laredo

Marathon de Laredo is a single-distance event in Laredo, Texas, on November 8, 2026: the full marathon, 26.2 miles through the streets of the city. The course stays in the urban core of Laredo, a border city with Mexico in south Texas.

With no shorter option on the day, this is a race to enter deliberately. A first marathon takes roughly 16 to 20 weeks of building, with the weekly long run stretching toward 18 or 20 miles and easy weeks worked in to absorb the load. If you are chasing a Boston qualifier, the session that matters most is a block of marathon-pace running inside that long run, and the discipline that matters most is holding goal pace through halfway instead of banking time. Rehearse your drinks and gels in training so nothing is new at mile 18.
