Revised Bolder Boulder Training Plan

Pott's Field is closed to the public during construction so my planned Tuesday track sessions are gone. Instead I'm doing 5x800 on the S Bldr Ck trail. I weighed 157 lbs this morning and I keep dropping. This is at a weekly mileage of 41 miles. Currently I'm running Easy (4) - 5.5 mi, Intervals (2) - 5x800, and Long (1) - 10 mi. After April 22 and the Earth Day 4K I plan on increasing Easy to 6 mi and the intervals to 6x800. How much weight am I going to lose then? I still have a fat tire so I hope I have some leeway.
