THE RACE

Live the experience of running on the trails of Aconcagua Provincial Park, and reach Confluencia Base Camp. Don’t compare it to any regular Half Marathon — our 25K will take you farther and higher.

While the main challenge is the altitude, the unique out-and-back trail to Confluencia Camp will keep you focused until the end. After passing the legendary Puente del Inca, you’ll enjoy a spectacular day with the Colossus of America running beside you.

Remember that your race entry does not include the Aconcagua Provincial Park entrance fee, which must be paid separately.

Argentine runners: the park fee will automatically be added as an extra payment, including the payment platform fee.

International runners: the park fee is paid in cash during accreditation, in the currency required by the Aconcagua Provincial Park.

CAN I CHANGE MY DISTANCE?

Yes, you can change distances as long as there are available spots and your registration is fully paid.

  • If switching to a shorter distance, the price difference is not refunded.
  • If switching to a longer distance, the runner must pay the fee difference.

How do I request a distance change?

All distance changes must be requested exclusively by email at info@aconcaguaultratrail.com

CAN MY FAMILY / FRIENDS COME WATCH THE RACE?

Yes, absolutely. Just keep in mind that if the start line is in Horcones (inside the Aconcagua Provincial Park), they must pay the day-pass to enter the start area. The day-pass is purchased directly at Horcones, at the entrance to the Aconcagua Provincial Park.

Otherwise, they can see you from other points along the course outside the park. Check your course map here.
