Nado en río 3 km Y 5 km

In the colonial era, the banks of the Yautepec River were home to indigenous healers whose clandestine health traditions were often suppressed by the Church. Today, this same water serves as the stage for one of Mexico’s most distinct sporting challenges. The river is fed by a first-magnitude spring that discharges between 6,700 and 7,000 liters per second, a geological force that has carved the landscape for roughly 10,000 years. As you navigate the 3 km or 5 km course, you are essentially swimming through the heart of this ancient, high-volume flow, where the current shifts from a steady push to a demanding resistance that tests your technical proficiency.

Historical currents

Beyond the natural flow, the environment is deeply marked by the memory of the Mexican Revolution. In June 1916, General Emiliano Zapata established his military command in Tlaltizapán, utilizing a local mill as the headquarters for the Liberation Army of the South. Swimmers today can spot remnants of this era along the riverbank, a somber contrast to the pristine, clear water. The town itself takes its name from the Nahuatl words for land and white powder, a nod to the prominent white hill that defines the local topography. Nearby, the ruins of the Temilpa ranch mark the site where Francisco Ayala, a central figure in the War of Independence, was captured. While the area holds deep historical weight, the swim remains a fast-paced athletic pursuit, with rules that permit the use of wetsuits or fins in a separate competition category. If you are looking to balance this river experience with other challenges, you might consider the Cruce Teques scheduled for mid-August, or for those drawn to the unique atmosphere of these springs after dark, the Night Swim offers an alternative perspective on the same waters later in the season. With registration tiers starting from 43 EUR, the event includes timing, a swim cap, and a medal, ensuring that your effort across these constant, spring-fed temperatures is officially recognized.
