Medio Maratón Internacional de Tijuana

The Medio Maratón Internacional de Tijuana is the border city's flagship road race, staged by the municipal sports institute (IMDET) and reaching its 31st edition in 2026. Run through the streets of Tijuana in Baja California — Mexico's busiest land-border city, directly across from San Diego — the course starts and finishes beside the Palacio Municipal and covers the full 21.0975 km certified by World Athletics. With a 6:00 a.m. summer start to beat the coastal heat, a field capped at 6,000 runners, and a prize purse exceeding one million pesos, it draws a strong binational and elite Mexican field. Nine hydration stations line the point-to-point loop, and age-group categories run from 18 to 75-and-over alongside dedicated wheelchair, visually-impaired, and best-local-resident divisions. The race is a fixture of Tijuana's municipal sporting calendar and a signature summer event for the northern Baja running community.
