More than 100 runners took on the challenges of the 100-kilometer Vulcano Ultra Trail 2025, starting from Lake Todos Los Santos and traversing demanding terrain such as Osorno Volcano and Jurrasic Ravine.

A grueling journey awaits. Over one hundred runners lined up for the start of the 100-kilometer race at the Vulcano Ultra Trail 2025, the most demanding leg of the competition.

The most daring competitors gathered at Lake Todos Los Santos, within Vicente Pérez Rosales National Park. This year’s event features six categories: 100K, 50K, 35K, 21K, 13K, and 8.5K.

A total of 114 athletes began the challenging course, which includes sections passing by Osorno Volcano, Jurrasic Ravine, and Teski Refuge.

However, organizers estimate that 40% of the runners will not reach the finish line, a testament to the difficulty of the event, which tests even the most experienced competitors.

The other categories of Vulcano 2025 will start this Sunday, December 7th, beginning at 5:00 AM.
