I really want know if there's and end to the Polar Plunge? Perhaps a beach? That's what I heard. Thnaks for viewing this and (maybe) answering my question.
Yes, there is an end to each Polar Plunge course (but no tropical paradise, though )!
The most common course to finish is the Polar Plummet course. The end to it comes after a score of about 9100 - 9700. At the end there is a tiny snowman waving a flag that marks the finish line. The great thing about the end of the course is that there is a chance on winning a trophy after each completion! The odds are about 1 in 3 of winning a trophy after completing the course.
Here is a picture I took moments ago of the end of Polar Plunge:
