This week was 62 miles of running and 4000 yards of swimming -- training log is here.
This was a bit of a tough week. I'd been feeling run down and fatigued for the past few days, but I stuggled on Tuesday's hill workout. My legs felt very heavy, and I was wheezing. Eventually, I got kicked out* of the workout by my teammates- a first.
(and by kicked out, I mean that when, after struggling up a hill, I gasped something about perhaps taking a few seconds to catch my breath, my teammates emphatically supported me and convinced me to drop. I have awesome teammates.)
There's many possible explanations for this, including the simplest (but oh so hard for us over-analytical types to accept) - it might just have been a bad workout. They happen.
But the same time there was a potential suspect. About 10 days ago I had doubled my dose of the drug I take for my Raynauds, Nifedipine. It's a calcium channel blocker that's very well tolerated by athletes, including a lot of runners, and so I hadn't been anticipating any issues with the increased dose (I've been doing really well on the lower dose - we just increased because I was still having a few Raynauds attacks).
However, there did seem to be a correlation between my increased dose and my dead legs and strained breathing - it was really within the past week or so that I had just been dragging a bit more each day - which matched the time I'd been on the increased dose. So, I contacted my doctor, and we dropped the dose back down to see what that did. In the days since, I've been feeling a bit better each day. Placebo effect? Who knows. In the end, doesn't matter that much - I just care about the end result.
I also got my ferritin checked again this week - I check it pretty regularly, both when I'm running well and when I'm not. And yup, it was down again. So, back on the iron supplements. When I was googling Nifedipine, I noted that it's now being researched as a possible treatment for iron overload in humans - it has been shown to cause iron loss in small animals. So maybe a connection between the increased dose and the drop in my iron. Or not. Who knows.
But good news is that I've been feeling better. I did crash and burn during Sunday's long run, but that had nothing to do with anything other than the fact that it was pretty hot out there. And both the bad workouts and the good ones are pebbles in the bucket of one's fitness.
And even on the humidest or lead-leg-iest of days, it's damn good to be out there.
