A dangler is a misplaced modifier. Your sentence is a runon sentence.

It is that, too!
Ms. Sue is correct in that this is a run-on sentence. It's two sentences. The first sentence modifies the second, so, in that sense, is a misplaced modifier, but it is not a phrase within a sentence, it is a different sentence. It's also convoluted in that "It is not the easiest thing to do" is expanded, modified, elucidated by the "challenging and exhilarating." I could rewrite it as one sentence or as two.
Ms. Sue, run-on was incorrect
Run on and dangler are both incorrect. I am not sure of the correct answer though but i was marked wrong for both answers in two attempts.
answer is- lacks parallel parts
