First Key workout for the week

It has already been a long training week.  I am in the middle of week 4 on my marathon training schedule.  I completed my key workout number 1 for the week on the treadmill.  It was 3×2 at MP with a half mile recovery between repeats.  I felt pretty good.  My  MP or marathon pace is 8:00 miles.  So doing 2 mile repeats at the 8:00 pace was not a big deal.  I ended up with 7 miles for the day.  I am still not totally convinced that I pull off a 8:00 pace for St. Louis….
