The Cross Nudista race will return to Yatan Rumi Naturist Reserve in Argentina’s Córdoba province on Dec. 6, with 3-kilometer and 6-kilometer routes.
The trails run through the hills and streams near Tanti, at an elevation above 1,500 meters. CNN Brasil, citing Argentine broadcaster TN, reported that adult participants run nude. Hats and running shoes are allowed, and women may choose to wear a sports top.
Local event information for the 2026 race lists participation for people 18 and older. It also confirms the two distances and the Dec. 6 date. The event is held at Yatan Rumi, a naturist reserve in the Córdoba region.
Organizers emphasize respect for other runners and the natural setting. Participants are asked not to stare at others, to respect personal space and to avoid loud music or other noise that could disturb the reserve. The race is open to visitors traveling alone, as couples or with family, though the local registration listing sets an adult age limit.
