Nancy5012 you are welcome. Enjoy the run, enjoy the improvement-but remember to take it slow to avoid burnout. That was the hardest part for me, I am a go getter but in running it is easy to start out too fast and get hurt or burn out. I took that bit of advice and am enjoying running! You should feel confident-you are DOING something instead of TALKING about doing something.
I had a similar experience at a sporting goods store when I was buying a pair of shoes. I went right up to the clerk and said "I want to see a pair of Saucony Cohesions in size 8.5 please." The clerk looked at me and said "you must be a runner." That was my first ever real running shoe purchase and yes I did my research before buying my shoes. But to hear someone else say I am a runner made me feel good.
EMTTrix said is right when she said a 7 minute mile or a 14 minute mile, is still a mile: run it. yeah we got this.
