Brand new to everything

Hi all!  I am brand new to triathlon.  6 months ago I wouldn't even have thought of it, but then they put the darn Olympics on TV and now, here I am.  Last year I turned 40 and decided to make some life changes.  I changed jobs, did yoga teacher training, and lost 15 pounds.  I just turned 41 and feel like I need to keep going.  Yoga is great, but it isn't enough.  I used to run 5Ks, I've been doing 30 mile charity rides once a year, and I know how to swim.  So maybe this will work for me.  I'm starting with the aggressive couch-to-5K plan, since I haven't run for a few years, with the hope to do a sprint-distance race next spring.  I live in NJ, and I'm married and have 2 kids.  Looking forward to getting to know some of you.
