I went to Jangsu, down in Jeollado, for the weekend and ran a 70km trail race with a cumulative 5,000m of ascent. It took me 17 hours. Proud of myself and grateful that my body can do that.
It was a lovely, really well organized race, with friendly people running and friendly people cheering and manning the aid stations. One lady even ran with her dog!
Inwangsan is a never ending treasury of hidden things. I have hiked this mountain hundreds and hundreds of times but there always seems to be another path I haven't seen before with a little shrine or some old military installation. Today we have a staircase to... I am not sure what on the side of the hill. There's statue at the bottom that looks like a Buddha but is labelled as the 산왕대신 Shamanist mountain spirit (there is a lot of Buddhist/Shamanist syncretism in Korea and lots of it in evidence on this mountain), and a small collection of rocks at the top. And a very unofficial mountain-goaty track behind that leads further up the hill if you are brave enough. I was brave enough to go part of the way, but stopped when I would have to start scrambling up rocks. I know where the path ends up anyway so there was limited motivation to go further.
