I did a few miles of bike ride Monday and got out for a run today. Whatever the reasons, this 2-mile run was far more difficult than any of the half-marathon. What the hell?
It wasn't the legs. I felt minor shin splint on the left, but nothing major, and I attribute that to using the newer pair of shoes, not the old broken in ones I've been running in. The lungs were in hell. I coughed the entire way, spitting up loads of junk. I don't think I spit anything up during the half-marathon. Could it be the 30-degree temperature drop? The 50% humidity drop? The fact that I've been doing all my therapy, including the hypertonic saline, for three days and that tends to irritate the lungs a little bit anyway? I mean, how does one go from a relatively-easy half-marathon with no lung issues to speak of to all of a sudden gasping for oxygen at a twelve-minute pace?
I'll see how Friday's run goes (planning 4 miles) and if I like it, I'll sign up for the Manhattan Half, which is Sunday. If I don't think my lungs can handle the cold, dry air for 13 miles, I'm not going to risk a repeat of lasts year's 3+ hours disaster and I'll just go volunteer or something.
