Ice exists all over the solar system and beyond, and NASA is exploring ice and how it changes.
Mars has bright polar ice caps that are visible from telescopes on Earth. The ice and snow (carbon dioxide) retreats in seasonal manner over the Martian year, the exact same as on Earth.
The Space Athletics Federation® (SAF) already has a couple of decades of experience in the icy polar regions of Earth. SAF co-founder Richard Donovan established a marathon at the North Pole in 2002. Participants, who included SAF co-founder Raphael Roettgen, literally ran ‘on’ water, the 6-12 ft of ice that covers the Arctic Ocean. Hence, the event could only occur in April, immediately after the Northern Hemisphere winter, when the ice had not retreated and was still robust enough for a plane to land.
Richard also established a marathon at the opposite end of the planet,which occurred in December during the Southern Hemisphere summer. Unlike the Arctic, Antarctica is a continent and marathon participants run on land rather than an ocean, albeit covered in snow and ice of considerable depth.
There was constant daylight at the North Pole and Antarctica when the events were scheduled.
