Narrative

The 43-year-old ran alongside penguins and battled severe wind and temperatures as low as -35C - the coldest organisers have ever seen - to cross the finish line in second place overall in a time of 17 hours 31 minutes and 39 seconds. Due to the harsh weather conditions, the race was brought forward to start at 1am on Sunday morning and Case says it was as much about survival as performance.
