Thank you all for replying to Jennifer M's post!!!

Don't just think you can ....KNOW you can ! You can and will !

 no worries, you will get there much sooner.   I always encourage folks to set two goals -a short term reachable, and a "mount everest" goal.  So pick a 5k, then pick a 13.1 (soon as you think you can get through a 5k without walking much, I would aim for a half about 4-6 months out - just a suggestion).  I did my first 5k in jan, first half in April and first full in Oct last year, and others have done much more than me, so it can be done!  

Glad I read this post. I've been so intimidated by everyone here since y'all are in such great shape. I might be brave enough to actually ask a question every now and then now! Everyone seems so nice and willing to help the newbies.
