The former Lead Designer Andreas Suika was asked if he wants to do a speedrun of any game at the speedrunpanel at the MAG-Convention. More jokingly he suggested TLJH, and set an hour as doable guesstimation.
During his stream this evening he tried a practice run to set the following rules:

1. Seed: Speedrun (contains glukkt, meorcl, ilitza and cueddhaest)
   
2. Free choice of crew, ship and lander
   
3. Difficulty: Story Mode
   
4. Timer starts once you load into the map and can actually do something/fly.

Andi made it home (with all crew alive) within 1:10:58± (not on the first try).
Feel free to try this challenge yourself and beat the time, or watch the VOD of the (german) stream at https://www.twitch.tv/videos/488444546 and see how he tries to do something with his game which it really is not made for.
