Weather: 65F (18C) and windy. Not much of a factor today.
The workout: 16K easy.
How I felt: Great for 5K, then OK until 12K, and then my legs just gave out. Lungs were fine, but my legs got heavy and had nothing left, like my 20K last week. This didn't hurt as much, simply because it was shorter and my legs got heavy at 12K with only 4K to go rather than at 8K with 12K to go. I expected this workout might be tough because of the 8K fartlek yesterday, and it was, but it could have been worse.
Total time: 1:41:19 for 6:20/km with ave HR of 142. My heart rate actually got lower at the end when my legs had nothing left and I just couldn't push. 5K splits: 30:31, 31:19, 32:19. 8K splits: 49:20, 51:41. Clearly hurting at the end.
