Seventh Edition 4 February, 2023

The seventh edition of Ultra Fiord® will take place on Saturday, 4 February 2023. We will return for the second time to run in the middle of summer in Patagonia. Compared to the first editions, which took place in April (Fall in Patagonia), we will expect warmer temperatures, less chance of precipitation, maybe a bit more wind, and days with much more sunlight. We still must be prepared for everything!

The race routes are located in the same wild area that has marked the character of Ultra Fiord® since its first edition. Some race segments still remain, but the new model launched in the previous edition allows us to access additional lookouts with amazing panoramic views. The race distances for this new summer edition will be: 55K, 42K, 28K & 16K. Previous race experience is required for all race distances and each runner must go through a selection process in order to confirm participation.

PUERTO NATALES is the ciudad base for Ultra Fiord®. In the days leading up to the race, the city will serve as the base for kit pick-up and center of operations & information for the event. In addition, the official buses will leave to the Starting Lines from the city and return here from the Finish Line as well.

Considering the established regulations in Chile to control the pandemic, all runners must have a verified and valid Mobility Pass in order to participate, which means all runners must have completed the vaccination process to protect against COVID-19.

Before registering for Ultra Fiord® it is your responsibility to review the General Rules & Regulations, in addition to the map and elevation profile. We invite your to explore the photo galleries from previous editions in order to have a better idea for choosing your race distance, selecting your clothing and planning your trip.


The event will be held in the Province of Ultima Esperanza (Last Hope), Magellan and Chilean Antarctica Region. The region’s capital is Punta Arenas; however, the closest town and logistics center to the course is Puerto Natales (Lat. 51º 44`S), which is 250km away from Punta Arenas.


For Ultra Fiord®, the meteorological conditions drastically dictate the level of difficulty on race day. In southern Chilean Patagonia, the difference between a good day and a bad day can be enormous, and within a few hours, we can go from sun and calm weather, to wind and snow. As a reference, during the month of February, in Puerto Natales (which is just about at sea level), the temperatures are historically between a maximum of 30ºC and a minimum of -3ºC, with average temperatures being around 14ºC. In general, it is a month with very little participation; however, winds can be a very important factor. Unlike previous editions, we will now run in the middle of summer, so different precautions must be taken and one must always be prepared for the worst conditions. This implies that each runner must arrive well-trained for their chosen distance and have chosen responsibly the necessary equipment for running in the mountains and these latitudes.
