So, trying to not keep track of times right now. But it sure seems like I'm getting fast. And I couldn't help but noticing the last half mile of a 12 or so mile 2/2 interval run, that I started walking almost right at the half mile marker, then after 2 minutes of walk did two minutes of run and almost made it to finish.

Knocking out half a mile in just 4 minutes of a 2/2 is pretty good. Better than most runners ever manage. And really feel like I could go a lot further. Worried about going too far towards volume and away from intensity though.
