Ultramarathon Trophy in Dying Light 2 Stay Human
Travel at least 960km.
How to unlock UltramarathonThis trophy will be a huge grind, as most of the time you will use the Paraglider and this doesn't count for this trophy. There is also no tracker available in the game so after you're done with everything else, go in a safezone and use a rubberband to turn around in circles, then go do something else. You're looking at probably 30-40 hours of running in circle but unfortunately you'll have to keep an eye out on your game as it can randomly pause.
