total running time 42:10. walked 1-1-1. I ran faster at the beginning and it didn't seem hard. at 7 minutes I went up tempo for 2 minutes and then hard for 1 minute. felt great during the walk break. at 18 minutes I went up tempo until the turn around at 20 minutes and then went hard for 1 minutes. I felt crappy from there out. My turn around was the farthest I had ever made but the return was painful. I wasn't really able to up-tempo at 29 minutes but I did go hard for a minute before the last walk break. from there on out it was slogging.
