Type 1 fun is something that you do voluntarily and it's enjoyable in the moment. My best example would probably be playing on stage when you're not nervous, you're playing well, the rest of the band is playing well and the crowd is dancing. I have type 1 fun at track days after all the preparation is done and nerves have subsided. There is also plenty of type 1 fun available at rock climbing.
Type 2 fun is something that you did voluntarily, that you didn't enjoy it while it was happening, but that you're happy with after it's finished. I can think of some motorcycle and car journeys that were horrible in the moment, but I was delighted to have done them. I did a climb recently that was fun in the first half, but the rest was so difficult and frightening that it was deeply unpleasant. I actually got down from having done it and said "that stopped being fun half way up" however I was really pleased with myself for having done it.
And then there's the much more esoteric Type 3 fun, which is neither enjoyable in the moment nor in retrospect.
