I ran 28km yesterday

To be honest, with my current ability,
my knees start to hurt if I run
20km at a 6:00/km pace...
Yesterday, I started from Mapo, crossed Seogang Bridge, and then crossed Haengju Bridge,
and it turned out to be 20km.
Like clockwork, my knees started aching from that exact point.
I picked a bad course, and from there back to Seoul, there were no cars and it was just a single narrow road...
I had to walk for over an hour to get to Mapo-gu Office to take the subway back lol
So it wasn't really 28km; it was more like running 20km.
I'll try to increase my distance and challenge myself with a 30km run.
Since I don't focus on setting records when running,
I'll get there eventually if I just keep at it lol
