Regarding whether you need crampons when running on the Antarctic racecourse with running shoes, based on my experience, the racecourse in Antarctica is not a pure ice racecourse, but rather a snow-covered racecourse, meaning snow covering on top of the glacier.
Racecourse Conditions and Equipment Selection
When running, we're actually treading on soft snow. Some areas are softer, some are more compact, but basically there's no slipping, because there's almost no exposed ice. So the conclusion is that you don't need crampons. Of course, road running shoes definitely won't work either, because they don't have enough grip.
The best choice is trail running shoes with very strong grip. You don't need those trail running shoes with metal studs. Regular trail running shoes are the most suitable.

Simulation Training Suggestions
This involves a common question: it's difficult to find terrain similar to Antarctica for simulation training. However, doing some long-distance slow running on the beach is helpful, because running on sand has a soft feel with some energy loss, and this is very similar to the effect of running on snow-covered glacier in Antarctica.
