Going into the workout I was feeling good. During the warm up the legs felt a little heavy but my HR remained fairly low and during a 2 min prep at 21 mph during the warm up the legs responded well. The first three intervals felt almost identical, but I could tell I was getting progressively more tire by interval 4 and 5. I finished the last interval strong maintaining nearly the same speed/power as the first interval. In fact in the last minute I was able to kick it up to over 22 mph.
