I am 45 and a new runner, 30 lbs over weight and really out of shape. On week 1 day 2, after my run, I battled to stay awake all day. A few days later I ended up sick - sore throat, cough, laryngitis so I thought I was tired because I was getting sick. I kept going and while often tired did not experience that level of fatigue again until today. I have done fairly well. Week 2 went well although I was definitely struggling at the end of each run. I did an extra day of week two because I was still battling being sick and didn't think I should move up yet. I started week 3 on Tuesday and did it - but those 3 minute runs were killer. I did day 2 today and it was pretty much the same. But by lunchtime (I run at 6:45) I was done. I slept most of the afternoon and have been a zombie all evening. I just want to sleep. I am eating fine. I eat half a banana before I run and then finish it after. I am drinking plenty of water. I did some research on-line and have seen that sometimes over training can lead to after run fatigue. Could this be the problem? Should I have stayed with week 2 longer? Anyone else have this problem? I love running and am excited that I am making this a habit now but I can't afford to sleep away my workday and my kids need me to be awake. :-) Any thoughts appreciated!
