Old Faithful (with a twist): 8 x 400m w/200m recovery intervals, but the fourth and eighth intervals were at a faster target pace and there was a 2:00 minute moving recovery interval after the fourth 400m.
I hit all my interval target paces pretty consistently. It took me until this workout to get my feel for my pace back. Now that I know where I stand I can start dialing up the intensity a little bit.
