I swapped tomorrow's run for today since tomorrow's going to be so busy. As I was having trouble working myself up to anywhere near my normal running pace for the second day in a row, I was flummoxed! Surely my poor diet over the last week couldn't have had that much of an affect, right? After all, it's never seemed to matter this much before... Then it hit me - I'd given blood on Monday night. DUH! Although blood volume can be replaced within several hours to 48 hours after donation, red blood cells take longer to be replenished. So I'm guessing that the blood donation, along with the poor diet the last week or so made for an especially bad combination this time around. I'm really hoping that by resting tomorrow, I'll be in better shape for Friday's long run - I'll just have to see I guess!
