OH honey don't be nervous! You're doing this for you and only you... no one else to impress, no one else's business unless you want it to be The biggest thing that you need to remember is that you're not alone. There are tons of us that have started C25K for various reasons and we're all in this together. Like Kellyb said, Just do it! I'm going to be honest with you I'm not a big fan of running. The fact is I pretty much hate life while I'm running... but I have fallen in love with the feeling that I have afterwards, and I'm REALLY loving all of the people that are asking me if I'm losing weight! Just ease yourself into it, don't be afraid to repeat weeks and push yourself. You'll be surprised by what your body can do when your mind will let it. Happy Running!
