get in shape to run a half marathon in under 1 hour 20 min.
Holy Crap! That's a 6:15 mile!

I haven't ever run that fast. My best 20 years ago was a 6:30 mile. If I could get to that fast again that would be sweet!
Thanks everyone for the input! Hopefully it'll work out and I'll get to post my story with a great buck!
