After missing two runs I was aiming to "make it up" with a swim last night. But just after supper my stomach decided to turn itself inside out, and I got a nasty headache. I never get headaches so things weren't looking good. I heeded my wife's advice (she is never wrong) and went to bed promptly at 9.
Thankfully I do feel better today, but still quite tired and my HR seems to be up a bit. A run is still in the works for today, but I will keep my fingers crossed anyways.
