Yasso 800s - A fresh start

I am looking for a fall marathon to run and with approx 18 weeks to go next week is week #1 of marathon training. Today was a great speed workout on the track with my brother-in-law, Mitch (it was his idea to incorporate into training). I plan to run Yasso 800s up to the marathon. Hopefully this will help me set a new marathon PR.
