Race Info
The Santiago Marathon (Spanish: Maratón de Santiago) is an annual road race first run in 2007 through the streets of Santiago, Chile, starting and finishing at La Moneda Palace. The event pairs the marathon with a half marathon and a 10K. It paused in 2020 and 2021 during the pandemic and resumed in 2022, and the 2026 edition (its 18th) drew more than 30,000 runners across all three distances.
