Here is the listing of water tables:
That's total craziness how many there are - the furthest distance between is 2.1 miles. I'll walk the duration of every water stop, but whether or not I drink largely depends on the weather. If it's warmer, obviously I'll drink more, but if it's cool, I can't overdrink, lest I need a bathroom stop.
My goal for the first half is to average 11:00 per mile, in the hope of not crashing and burning during the second half. If I can maintain a flat 11 average, I'll hit the half at 2:24, then have 2:34 to finish the second half and still PR, which would require an 11:45 average for the second half. It sounds so easy when I'm home at my computer playing with the numbers. We'll see how it plays out when I'm running.
