July 12, 2012 5miles

missed my run yesterday, had too much stuff to do when i got home and it was late when i got done. tonight i had a meeting at work that ran a little late, then went to eat with one of my partners, then got home late. i was trying to do a little research on the computer, which was extremely slow, then i finally got to run around 11:15pm. my legs felt tired. since the run was so late, i had to run on the treadmill. i was going to try and do a tempo run, my plan was to run the first and last miles at an easy pace of 10 minute miles then run the next 3 miles at 8 minute miles (remember i was on the treadmill). the first mile i felt a little tired, but figured i just needed to stretch my legs a little. at the end of the first mile i was feeling pretty good so i bumped up the speed. at mile 2 i had to slow down to 9:15 minute miles. a half a mile of that and i had to go back down to 10 minute miles. that is where i finished. being on the treadmill this run seemed a little hard. even after i slowed down i was still breathing pretty hard, which is good because i need to increase my O2 capacity. it is late and i have to work and run 4 miles tomorrow. goodnight.
