New goal: 10K next year?

I went to the gym tonight and ran just over 5K with little effort after about a month's hiatus from running....which got me to thinking perhaps I should work towards running a 10K race this time next year. It's only occured to me since Yonge St. was closed for part of yesterday because of a 10K race...is this crazy talk??? Hmmm....we'll see.
