I've always loved running and as a kid I practiced freestyle athletics which included a lot of track running. I'm rather light so it feels like I can run forever and I just love that sensation. I mostly just tend to run out of breath when I try running during mountain hikes but even then I can keep on jogging for a while. Running really feels nice especially when you're running in some nature dominated area but not in the middle of a city.
I used to practice freestyle athletics as a child so that included a lot of track running but I overdid it on my knees and got osgood schlatter and I never really picked back up on any sort of structured work outs since then, but I still enjoy running as an advlt even if it's not on a track.
