Hey Toese -- nice to see you here too!
I've been running since I was a kid -- on the track team in grade school, etc. My family runs, Dad is quite competitive, even at age 60, he run's 18-19 min 5Ks!! He's quite an inspiration -- esp since I've outweighed him since about age 17!

I ran about a race a month -- 5ks, 10ks, 10-milers, my longest and proudest was the Philadelphia half marathon. Great race, great course--fast and flat -- and lots of support along the way. Not sure if I feel the need to do a full marathon -- I'm not that fast, and I don't really want to be running for 4+ hours!
I run for fun, I'm not fast enough (or disciplined enough to be skinny enough) to compete -- races keep me focused, goals tend to help my progress. Fortunately, I have a husband and lots of friends who are very active, fit, run races, triathalons, etc. It helps to have race buddies.
I took a few years off running (unintentionally) pre and post my two children. But continued to be active w/other gym things! Yoga, step, kickboxing, weights, etc. I'm just getting back into running now and have a 7-miler planned for June! I'm comfortably running 3-4 miles now, so I don't foresee a problem increasing the mileage in a month or so.
I'm psyched to be a runner again. And even more excited for the great weight loss that comes with it. Toese, thanks for starting this post. It'll help keep me motivated!
