Assume that the earth is a perfect sphere with a circumference of 40Mm. Santa needs to travel from the North Pole to the South Pole while avoiding daylight. Assuming that he can go faster than the speed of light, what path would be the best path to take and what is the slowest he can travel?

To be clear.... the best path is the one that provides Santa the slowest speed (gives more time for gift giving)

It's hard to envision Santa being a tachyon at all, much less a slow one. And I'm not sure of the definition of best.

@bonanova
The path/strategy that allows Santa to continiusly travel around while remaining forever at "night" going at the minimum speed possible.

True but this task is about moving as slow as possible.  Though he can travel that fast, which is how he is able to deliver all those christmas gifts, we want to know what is the slowest he could go.
