"If you'd asked me at any point in the journey, I was absolutely miserable, but on the whole it was miraculous. Gained a ton of skills."

Sounds a lot like ocean racing sailboats under normal circumstances.

I quit ocean racing (after about 5 seasons) when I had a sudden realisation that the only part that was any fun in the last 3 days was sitting in the bar after it was over and talking about it. And there were ten times as many non-crew people there enjoying that with us as there were crew on the boat I raced on.
