I forgot to mention...
Right towards the end of today's run, at about 30 km, I was tired and trudging up a small hill on my route when a man jogging past me in the other direction looked at me and said, "You go, girl."
Normally, because I'm usually such a grump, I wouldn't have really thought much of this gesture. But today? It was perfect and just what I needed to keep going.
So to this random kind stranger: THANK YOU! Hope you had an awesome run.
