Antarctica ()

Pat Farmer (Australia) covered a distance of 1,198 kilometres (744.4 miles; 649.9 nautical miles) running from the Union Glacier Camp to the South Pole between 30 December 2011 and 18 January 2012. The journey time was 19 days 11 hours 50 minutes and he ran 50–70 kilometres (30–45 miles) for 15–20 hours per day.

This was the final leg of Farmer's unprecedented "Pole to Pole" run, having departed the North Pole on 6 April 2011. Across the full ultramarathon, it's estimated that he covered a distance of c. 21,000 km (13,050 mi) running an average of 65 km (40 mi) per day. The journey also raised A$100,000 for the Red Cross.

Guide Eric Philips accompanied Farmer (a former member of the Australian Parliament) as expedition leader for both of the polar segments of the Pole to Pole ultramarathon.
