Get faster

I am in a 7 week patch between immt70.3 and imaustin 70.3 training.
Endurance nation suggests that I do the Get Faster plan during this time.
I am, but loosely. I am also working in sessions at the track with my running group, and Crossfit classes and oly/power lifts.
Mostly, I am trying to build strength and speed without as much concern about endurance. Fun stuff.
Today, for instance the morning session was with my track group. After a mile warm up, the main session was 2mi as 1:00 on, 1min off. The goal was to get the 8laps done in 10 "on" minutes. But that comes out to a 5min/mi pace and that was a bit beyond me. My first interval was a 5:05 pace and I drifted as slow was 6:00 by the end. Still, a 6min pace really popped my hr and was pretty fast for me.
I am getting a power meter hub installed in my hed jet 9. Should be ready next week. Looking forward to testing and getting more specific in my cycling training.
