@CarolynA, welcome to the forum and WHAT A KILLER CURVE! As @docslotnick says, never waste a good low 
I see you are a runner and a swimmer, that’s great: we have many runners and swimmers here! You have an amazing A1c! My son (he is only 12) is a swimmer, and has aggressive A1c goals too!
If you wish, you might want to visit the introduce yourself thread. Welcome!
