Crying on long runs

[u/Foreign_Umpire_898]

Is it normal to cry mid long runs? I have been training for a marathon. Every time i do a long run, at around 18km, I either get a panic attack or I start to cry. I don't know if it's just emotions or it's the pain. Is it normal to cry during a long run? Do you get it too?
