My first "run" outside!

I decided to take a walk outside and did several 1 minute run intervals. It was the first time my running shoes have been outside! I have only worn them either on my treadmill or the gym and I change back out of them before I go back outside after working out. I did do this too close to the time I ate dinner, so I felt a little sick and with the good old sacramento valley muck we have I came back wheezing, but I will have to get used to running outside, I don't know of any 5K's I can run inside!
