Antarctica
The clock starts on the ice at Ultima, deep in the polar interior — sub-zero temps, 24-hour daylight, and the loneliest marathon on Earth.

The World Marathon Challenge — the original “777” — is one of the most demanding endurance events on Earth: seven full 26.2-mile marathons, on all seven continents, inside seven consecutive days. The clock starts the moment the first marathon begins in Antarctica and never stops.
Since 2015, only 292 people on the planet have finished it. In the 10th edition — Jan 30 – Feb 5, 2027 — I'm going to do everything possible to become one of them.
Seven starting guns. Seven finish lines. The 2027 route races east from the Antarctic ice to the streets of Miami.

≈ -15°F · Ice & SnowOff the ice and straight into summer beneath Table Mountain — a 90°F+ temperature swing in under 24 hours.
≈ 75°F · Coastal SummerMarathon three under the Western Australian sun, with the body now running on airplane sleep and stubbornness.
≈ 85°F · Dry HeatHalfway. 26.2 miles through the desert night skyline — usually run in the small hours between flights.
≈ 70°F · Desert NightWinter returns. Marathon five in the European cold, where the 777 is famously won or lost in the mind.
≈ 45°F · Winter ChillAcross the Atlantic to the Brazilian coast — equatorial heat and humidity on legs that have already covered 131 miles.
≈ 88°F · Tropical HumidityThe final 26.2. Home soil, one last starting gun, and a finish line seven continents in the making.
≈ 80°F · The FinishSeven start lines, seven finish lines, one lap around the planet.
All seven continentsDecidedly non-professional athlete who got hooked on endurance athletics. On January 30, 2027, I'll toe the start line of the World Marathon Challenge: seven marathons, seven continents, seven days. It's the hardest running adventurer I've ever committed to, and I wouldn't have it any other way.
