For the first time this year, I went running outside! It was really refreshing, but I should have put on one of my long sleeved shirts. There were quite a number of people running, you know one thing that I wonder about , when you meet a runner, running towards you, do wave, say hi, nod, acknowledge, smile or totally ignore? What is the running etiquette? It was a good 5.5 miles run. Hope I can do it again soon.
