My first half marathon was in Taipei. The full lenght of the race was on highways, and it was drizzling a bit. I saw a racer wore flip-flops, and later saw another one too!
The most memorable part was...I had to pee, it was around in between 10 to 15K. There were porta potties along the way, and I went to the closest one I could get to. So I jog across the empty highway, opened the door, and was welcomed by the horrid smell of human excrement. The floor was completely covered by the yellowish waste, but I had no other choice. I stepped in and relieved myself, while imagined how bad this guy must have felt.
Anyway, I ran a decent pace, then walk funny the days after.
Your compass is spinning lmao.
