I've been feeling a cold coming on for a few days. I think that Sunday's road bike ride brought it on because, even though the temperature was 72 F when I left, it was chilly in the shade. I only wore a light, sleeveless base layer and short sleeve jersey, so got kind of cold. Also, having some stomach problems and not sure what that is from. I need to take at least one day off from the bike.
I'm recovered from slight cold and feeling really good, actually. I think the rest day on Tuesday helped a lot.
