March 12, 2023


COURSE: The course will be routed over a roller coaster course toward Artigas, the Uruguayan Base at the western end of Collins Glacier. The course is entirely on dirt roads, which often can be muddy.  The course changes each year based on the base operations as well as road and weather conditions.  All runners must be self-sufficient and cannot expect any access to indoor facilities.  

CHARITABLE OBJECTIVE: Each year Marathon Tours & Travel offers runners the opportunity to sponsor an official Antarctica Marathon®️ and Half-Marathon Mile Marker(s). The proceeds of the Mile Markers are donated to Oceanites, which is the official non-profit organization of the Antarctica Marathon®️ and Half-Marathon.  In return, the runner gets to keep his/her sponsored mile marker after the race as a great souvenir! You can sponsor a mile marker by completing the Antarctica Marathon®️ Mile Marker Sponsorship Form.  Oceanites has been researching the effect of climate change and tourism on Antarctica for more than 20 years.  They have collected valuable data on wildlife and plant populations to support further research on this most pristine part of our planet.  In addition to the sponsored mile markers there is a live on-board auction during the tour with all proceeds also going to Oceanites!

TEMPERATURE: Average temperatures range between 15F-34F minus the wind chill, which can lower it by about 10F.  Heavy snow is rare but light flurries are common.  

COURSE TIME LIMIT: Marathoners must finish under 6.5 hours, weather permitting.  You must pass the halfway mark in three (3) hours and 10 minutes.  Half-Marathoners must finish under 4 hours, weather permitting. Course marshals have the responsibility to disqualify any runner who might endanger himself or herself through fatigue, hypothermia or dehydration.

NUMBER PICKUP: Race check-in and the briefing with emphasis on the environmental rules and regulations governing this event will be held at the welcome dinner in Buenos Aires.  Attendance is mandatory for participation in the race.  

SHOES: You will not need any special shoes.  A training shoe designed for off-road running is best.  Bring two pair since it might be wet and muddy. Racing flats are not recommended. NOTE: trekking poles or any other aid are not allowed in either event.


ELIGIBILITY:  All runners must be at least 18 years of age on race day for participation in the marathon. There is no age limit for the half-marathon..

AWARDS: The top three overall for males and females in both races will be recognized.   In the marathon, the top two in each age category will be recognized (under 40, 40-49, 50-59, 60-69, and 70 and over).  All finishers will receive a finisher certificate and a medallion.

DIFFICULTY: Very Difficult.
