The XLII Maratón de la Ciudad de México is set for Sunday, August 31, starting at Ciudad Universitaria and finishing in the Zócalo with official wave starts at 5:55 a.m. (wheelchair/visually impaired), 6:00 a.m. (elite women), 6:05 a.m. (elite men with Block A), followed by Blocks B at 6:15 and C at 6:30. Race kits are being distributed at the World Trade Center’s Salones Maya 1 y 2, Thursday–Friday 10:00–20:00 and Saturday 8:00–16:00, with in‑person pickup requiring ID, waiver and proof of registration. Free electric shuttle buses for bibbed runners depart from six designated city points from 3:30 a.m. toward the Estadio Olímpico Universitario or Av. del Imán, and Metro Lines 1, 2, 3 and 9 will offer free service from 5:00 a.m. with bib verification. Indeporte’s enforcement campaign will disqualify and remove from official results any participant who does not complete the certified 42.195 km course, reinforcing the event’s “Cero Trampas” message. Finishers will receive a Reconocimiento Painani marking 700 years of Tenochtitlán, organizers report roughly 30,000 registrants, a Rarámuri contingent is expected, and outlets list prize structures though reported amounts differ across publications.
