I BAILED on my 1/2 marathon. I did get up at 1:45am, after getting only about 20 minutes sleep, thanks to my neighbors who had a late fireworks party, so i got up, and HOBBLEd to the kitchen and had a cup of coffee, limped back upstairs, stretched out my leg slowly, showered and dressed and could not get that sciatic pain to subside!! I feel soooo defeated about this. But the Olympics are on during this time and NiKE got a commercial that just touches you to the core - finally, they just nailed it:

So Sunday, i walked the 7.5 on my marathon training plan - 16:10 pace
Tuesday, a good treadmill run - walked .25, ran a mile, walked 4 min, ran another mile, walked 3 min, and ran another mile - 3 independent miles of all running - 3.5 today in 46 min.

Then today - ta daaaaaah! I feel very good about this. 4 miles - 46 minutes - NO WALKING!!!
With a little reminder from a dailymile friend - Michelle from Georgia - i also did a COLD bath afterwards. She recommended ice bath, but here in Utah, remember our tap water is melted snow pack, so i think that is cold enough.
But i feel good about this, and will try to stay on this journey to Find My Greatness!!
