Speed intervals didn't quite go as planned.
First, instead of doing mile repeats, it was a reverse ladder. We started off with 1200 meters, and then decreased by 200 until we did a 200 sprint.
So much for concentrating on breath. I mean, I had to, but I couldn't compare apples to apples or anything. Mostly I just tried to finish each lap at a good pace, and most of the time I averaged 90 seconds per lap, or a 6 min/mile pace. It'd be more impressive if I could say I did it for longer than 4:30, but I didn't.
Whether I did a 400 or a 1200, I was only a second or two off a 6 min pace.
Except for the 200 sprint. I don't know if it was because it was the last lap and I stopped pacing myself, or if I broke through a mental block, or what, but I did it in 30 seconds, or a 4:00 min/mile pace.
Which, I have to say, isn't half bad. :)
