Note
So it turns out that I probably had only around 33 minutes of error total (4 and 7 actually only contributed 18:58, according to Winsplits), I could have run around 35:14, which equates to 22nd place in the B final. Main issues: underestimating the course, not being careful enough in the green, losing map contact in the green due to the previous error, et cetera. Also noticed that I was too relaxed, and not in "racing" mode, if that makes any sense. Definitely think that contributed to messing up so badly.
