Forewarning, the following images were created using Midjourney, largely building off a prompt for cinematic grading created by Everton Lisboa.
This sequence has been stuck in my head ever since I first read the novel Blue Mars by Kim Stanley Robinson. Hundreds of years from now Mars is in a partially terraformed state. Here one of the main characters, Mars-born Nirgal, joins a marathon which asks contestants to circumnavigate the entire planet across both highland and lowland environments. Due to the massive elevation differences a breathing apparatus is required while crossing some highland sections of the route.
Mars-born humans are on average taller than Earth-born humans, having developed in 0.38 gravity.
