Today was a threshold run. The workout was 20 mins at threshold pace, two minutes of rest, then a final mile at threshold pace. The target pace was 5:32/mile. I started slow, mainly because I always tend to go out too fast on these runs, shooting myself in the foot early on. I ran the first mile in 5:30 (approx.), two miles in 11:00 flat, three miles in 16:22, three and one half in 18:50, and another minute at the same pace. After a two minute rest, I ran a mile in 5:26. This type of workout is weird in a way. The objective is to work at the peak of aerobic ability, without ever going "anaerobic". This is a hard line to draw, but if you go by feel, it is much easier to determine correct pacing. All too often, an AT run is mistaken for a speed workout. This ends up working a completely different energy system, eliminating the whole point of a threshold run. Ok, don't really know where that came from. I did 8x150 meter strides afterward, and did a good cooldown. My leg hurt a bit at the beginning, but as time went on it stretched out and did not hurt too bad. Overall, the run felt really good! |
