2x1600 Ints

Made it out today using my iphone/runkeeper.  The goals was to start ramping up the speed.  After crossing the bridge, I did the first mile at 6:43.  Had to work not to run faster, good thing to since the next mile hurt a little more: 6:53.  Groin was sore during mile 1.  I backed off a little for the second one and it seemed to loosen up a little.  Stretched it good tonight - I'll have to watch it.
