Marine Corps Marathon. My marathon time was not bad, but not what I was aiming for - finished 10 minutes off at 3 hours 55 minutes. I ran with Jill, training partner and friend for 21 miles averaging 8:30 pace as planned. Then I was focusing on the suffering and painful quads won the battle - faded with increasing walking periods - getting into the 11 minute mile range. I was ok for energy but maybe electrolytes were off. Maybe pushed too hard in the first part with hills.
