I've had better days running. My left heel has been bothering me for a few days. Most likely due to the big downhills that I have been running. Started off with a 3 mile warm up run. My heart rate was a little high for the pace which I attribute to a head cold that I've had for a couple of days. Ran 5 miles at lactate threshold (hoping to hold the pace below 6:40/mile). First 2 miles felt really good (6:32, 6:31). I felt like I was running very smooth and in control. I had to work a little harder on the 3rd mile but was still able to hold pace (6:32). I really started to work during the 4th mile. I was starting to tense up and my stride did not feel as smooth. I wasn't overly tired but I was working more and my HR started to climb (6:38). I think that I mentally gave up at this point as I felt as though I was just going through the motions on the last mile (6:44). My HR was 167-168 for the first 2 miles then climbed to 175-180 the last 2 miles. Finished with 2 miles at a very slow pace. Not sure what my problem was today. My heel did not hurt at all during the tempo miles but was sore during the cool down miles.
Avg HR: 158
