can't shake the exhaustion.

Hello-

I had a sprint race on Sunday. Overall, it was a great success for me. This is my third year doing the race, and I shaved 15 minutes off my time, which I am so proud of. I have to credit my 1/2 marathon training for the massive time improvement! When coaches tell you to schedule in plenty of good base training, they're not kidding!

My problem is that since the race on Sunday, I have been absolutely exhausted! I had a good recovery meal consisting of a bagel with a small amount of peanut butter, and plenty of watermelon. I had plenty of hydration during the race, and consumed 2 Clif gu packs. After the race, I spent a relaxing day at home, and got plenty of sleep that evening.

I have continued to do small amounts of training this week, including a short 10 mile bike ride, a 3 mile run, and a mini triathlon on Thursday Sep 3 which was 1/4 mile swim, 10 mile bike, 2 mile run. Any thoughts on what I might be doing wrong here? I have to run 11 miles tomorrow morning because I have my first 1/2 marathon coming up Oct 4! I'm worried that I'm not going to be able to shake this... and can't seem to figure out what's going on. I go to bed around 9:30 and set my alarm for 6, but have been sleeping right through it, I'm so tired!

Thanks for any help or suggestions you can provide!
