Yoongi went on stage after finishing a marathon on the morning of the US concert.

An article came out on the morning of the Stanford concert saying that Yoongi participated in and completed a 12km marathon.
I heard they finished that steep hill course in 1 hour and 4 minutes, putting them in the top 5% of the participants; that's really amazing.
Everyone was worried because he was limping slightly towards the end of the concert that evening, but it brings tears to my eyes to hear it was the aftereffects of the marathon.
You mentioned running 10km a day to maintain your stamina, and I'm just so grateful that you performed with such passion on stage.
Seeing Yoongi, a genius at his main job who even set such a great record before the performance, makes me so proud. I hope he continues to tour safely and healthily without getting hurt.
