From Greenwich back to Greenwich, Danish ultrarunner Jesper Kenn Olsen linked long runs across Europe, Eurasia, Japan, Australia, North America and the British Isles. The World Runners Association records 26,232 kilometres over 662 days, from 1 January 2004 to 23 October 2005. Flights bridged oceans; the trace follows the documented endpoints of each continuous running leg rather than implying an unbroken land route.
In 1980, twenty-one-year-old Terry Fox set out to run across Canada on an artificial leg, asking Canadians to fund cancer research one dollar at a time. This trace follows selected documented milestones from the Atlantic at St. John’s to the highway outside Thunder Bay, where cancer in his lungs forced him to stop after 143 days and 5,374 kilometres.
From 17 September to 5 November 2006, Dean Karnazes covered a marathon distance in every U.S. state on fifty consecutive days. This compressed trace uses thirteen editorial milestones to make the continental scale legible while naming all fifty states; several weekend runs were live races, while most weekday efforts followed established marathon courses outside their normal event dates.
In July 2006, David Goggins made his Badwater 135 debut on the road from Death Valley’s Badwater Basin to Whitney Portal. He finished fifth overall in 30:18:54 during a race that reached 123°F and later brought rain, hail and flash flooding. This trace follows the official course checkpoints that shaped his breakthrough performance.
In 1984, Greek ultrarunner Yiannis Kouros covered the Spartathlon course from Athens to Sparta in 20 hours 25 minutes, improving his own winning time from the race's first edition. This trace follows the defining landmarks of that 245-kilometre crossing and the performance that established Kouros as an ultrarunning legend. His record stood until Fotis Zisimopoulos ran 19:55:09 in 2023.
In 1983, 61-year-old potato farmer Cliff Young won the inaugural 875-kilometre Sydney–Melbourne ultramarathon in 5 days, 15 hours and 4 minutes. The familiar claim that he never slept is an exaggeration: contemporary recollections say an alarm-clock mistake sent him out early on the first night and that he then slept very little. This trace follows the old Hume Highway towns behind the shuffle, the gap and an Australian sporting folk story.
1 January 2004
London, United Kingdom
Olsen began at Greenwich on New Year's Day, choosing the prime meridian as the cleanest possible line from which to run east around the planet. His first documented leg pointed across northern Europe toward the Finnish–Russian frontier.

2004
Virolahti, Finland
Virojoki marked the end of the 2,291-kilometre European opening leg recorded by the World Runners Association. The border ahead also marked a change in scale: the next continuous section would cross Russia to the Pacific.
60.5795°N · 27.7051°E
2004
Vyborg, Russia
Across the frontier at Vyborg, Olsen started the defining land section of the first World Run. The association measures the Vyborg-to-Vladivostok leg at 10,345 kilometres—almost forty percent of the entire recorded run.
60.7139°N · 28.7325°E
2004
Vladivostok, Russia
Vladivostok closed the longest documented segment: a trans-Russian run from the Baltic edge to the Pacific. Ocean travel was never counted as running distance; Olsen next resumed on land in Japan.
43.1155°N · 131.8855°E
2004
Niigata, Japan
Olsen restarted on Japan's Sea of Japan coast at Niigata. The 846-kilometre run to Tokyo was short beside Siberia, but it kept the World Run's method consistent: fly across water, then continue on foot across the next landmass.
37.9162°N · 139.0364°E
2004
Tokyo, Japan
Tokyo ended the Japanese crossing. Olsen had now connected Europe and Asia with a separate island leg; the next flight carried him to Sydney for a full-width crossing of Australia.
35.6812°N · 139.7671°E
2004–2005
Sydney, Australia
Sydney opened a 4,670-kilometre westward crossing to Perth. Reversing the apparent eastward rhythm on the map did not change the purpose: Olsen was accumulating a defensible global running distance across successive continents.
33.8568°S · 151.2153°E
2005
Perth, Australia
At Perth, the Australian leg ended on the Indian Ocean. The run's geography was made of enormous foot sections and explicit transport gaps—not a claim that anyone ran across the oceans between them.
31.9523°S · 115.8613°E
2005
Los Angeles, United States
Olsen resumed in Los Angeles for the last giant continental stage. The association records 7,690 kilometres between Los Angeles and New York, a coast-to-coast run extended far beyond the most direct road line.
34.0522°N · 118.2437°W
2005
New York City, United States
New York closed the 7,690-kilometre North American leg. One Atlantic crossing remained before Olsen could bring the route back to its Greenwich origin.
40.7128°N · 74.0060°W
2005
Shannon, Ireland
After flying the Atlantic, Olsen began the final recorded running section at Shannon. The World Runners Association groups the Irish and British finish as a 555-kilometre leg back to Greenwich.
52.7039°N · 8.8642°W
23 October 2005
London, United Kingdom
Olsen returned to Greenwich after 662 days. The association's total—26,232 kilometres—counts the running legs, while this final point gives the undertaking its narrative circle: the same meridian, nearly twenty-two months later.
