The city you want to run becomes your next trip.




THE DREAM
A 250 km stage race run on the Antarctic Peninsula, reached by ship across the Drake Passage.
Each day the course is held on a new stretch of coast, and the race is known as the final desert of the 4 Deserts series.
The field is limited to just 40 runners.
Picture the course in advance
and find the pace that fits you.
Streets lined with cheers, runners all around.
You'll be part of that scene.
Take it slow with the finish still in you,
and meet the city all over again.
From the joy of finishing to the tough moments — read what runners wrote themselves.
“This one was challenging because of the ever-changing soft snow we raced on.”They finished their fourth RTP race. Their pack was light at 2-3kg, and they say the whales and the swim at Danco Island stood out.
“The travel and journey to 'the end of the world' and Drake's Passage onwards to Antarctica is absolutely worth it”They say the snow was bumpy and icy, so micro spikes mattered on 4 of the 5 days. They advise reading an expedition book beforehand.
“the magic was never held in the places. But the people in those places.”61 people crossed the Drake Passage, and one runner stopped stage 4 early because of leg and back injuries yet still finished. They say the deep snow and wind were tough.

changes with each edition
The race begins after a two-day crossing of the Drake Passage by expedition ship from Ushuaia.
The ship is both your accommodation and base camp, and each day you land by inflatable boat and run that day's course.
The course changes with each edition;
in 2024 it was held at Half Moon Island, Deception Island, Dorian Bay and Danco Island.
Each stage is run as a timed event on a looping course of roughly 2–14 km,
where you complete as many laps as you can in the allotted time, and across the 6 stages you can run up to 250 km in total.
The course is marked with ski poles and pink snow bags, so no navigation is needed.
Many sections have deep snow or an icy surface, and if penguins or seals appear on the course, you must give way.
Daytime temperatures range from -2°C to 5°C, nights fall as low as -10°C, and the sun stays up for nearly 20 hours a day.
In 2024, 78 runners from 37 countries stood on the start line, and it was the 10th edition.
The 2026 edition is the 11th.
In bad weather, the locations and number of stages may change.
Pick up your bib, check your wave.
So on race morning, you can just run.

Before you apply, first check that you have completed at least 2 ultras from the 4 Deserts family.
The Entry fee of US$14,900 covers 10 nights (11 days) aboard the ship, meals, medical support and the finisher medal.
Flights to Ushuaia and local hotels are not included.
The usual route to Ushuaia is via Buenos Aires, and it is safest to arrive one or two days before departure.
In 2024 runners boarded on 26 November, and the first stage was held three days later.
The surface was soft, churned-up snow, and runners who brought microspikes reported finding them useful on four of the five days.
One race report describes packing the backpack light, at around 2–3 kg.
Be sure to bring windproof and insulating layers, sunglasses and goggles, and sunscreen.
The glare is intense, so watch out for snow blindness and sunburn.
If you are worried about seasickness on the Drake Passage, bring medication in advance.
In Antarctica you must keep your distance from wildlife and follow biosecurity procedures, which include removing soil and seeds from your clothing and shoes.
There are also programs that allow family and friends to join you aboard the ship, so check the official website.
Times are local to Ushuaia. Check the latest official information before the race.
