14o Gran Reto Aguas Abiertas Zirahuén

The morning of the 14th Gran Reto Aguas Abiertas Zirahuén begins long before the first swimmers take to the water. As the village of Zirahuén stirs, the local community and the organizing team led by Edgar SG prepare the shoreline, a tradition that sees families return annually to this quiet Michoacán corner. The atmosphere is one of focused anticipation, rooted in a history that stretches back to the Purépecha people, whose presence in the region was noted in the 16th-century 'Relación de Michoacán' during the youth of the leader Tariacuri.

The Mirror of the Gods

Swimming the 5km course, you are effectively traversing the 'Mirror of the Gods', the translation of the lake’s name. The water is of volcanic origin, formed when lava from the La Magueyera volcano blocked the La Palma river, creating a deep, mountain basin that reaches 43 meters. As you sight, you will notice the traditional wooden 'trojes'—the distinct regional houses—perched among the dense pine and oak forests that frame the water. On the shore, the parish of the Señor del Perdón stands as a reminder of the missionary era, its wooden barrel-vaulted ceiling a craft rarely seen elsewhere. If the winds are calm, the water’s surface reflects the forest canopy, creating the visual phenomenon that gave the lake its name.

Legends and Lake Dynamics

Local lore persists beneath the surface. The legend of the princess Eréndira, who was allegedly transformed into a mermaid to escape a captor, remains a staple of local stories; locals still caution that her spirit haunts the deeper sections. While you will not encounter any mermaids, you might notice the water’s clarity, though heavy storms can sometimes trigger runoff from surrounding agricultural areas, occasionally tinting the edges of the lake with a reddish hue. The lake is monomictic, stratifying between April and October; while surface temperatures fluctuate, the deeper layers remain consistently cooler. The ecosystem is fragile, hosting the endemic Zirahuén allotoca, a small fish found nowhere else. For those looking to compare, the regional calendar includes other events, such as Zirahuen Open Water, though this 5km challenge remains the primary test for those drawn to the deep, mountain waters of Michoacán.
