The people who put start lines in impossible places.

Runbuk has been doing this since 2003: on Arctic sea ice at the North Pole, on the Antarctic ice sheet at 80° south, and across seven continents in seven days. Hundreds of runners from fifty-eight countries have crossed a Runbuk finish line at the top or the bottom of the world.

Seven Wonders Marathons™ is the same organization pointed at the opposite kind of place — not the emptiest points on earth, but the seven most recognised. The same race directors, doctors, timers and logistics crew travel with you.
