If in fact I have not totally overdone it (I don't think I have) and am just close to it, does this sound like enough time of recovery to get back to normal leg energy, and let my resting HR go back down (if it is even elevated)?
Your "problem" is very interesting, it sounds very familiar to what I have experienced a couple of times!
I recently did a few weeks of training with higher intensity and longer rides than normal. The last weekend I felt tired and my legs were really heavy. On the Sunday ride my legs were totally empty, but I ate a few choclates and drank sports drink, and my legs opened up during the ride. However, when I got back I felt really tired again and my breath smelled ammonia! (If you deplete your glycogen stores, your body burns more protein (your precious muscles) and in extreme(?) cases your breath can smell of ammonia).
Monday I went on a one hour recovery ride, but my legs almost wouldn't move, I was totally exhausted.
During this whole training period I had also been trying to loose weight. I mainly ate food with low/moderate glycemic index, and restricted my intake of carbohydrate in general.
When I got back from the Monday recovery ride mentioned above, I thought maybe it was time to eat some carbohydrates. I had some pasta, and all of a sudden I had a feeling of hunger like I had not had in many weeks. I ate more pasta. During the next few days I was so hungry!! I ate more pasta, bread, etc than I had in a long time. At the end of the week my legs were back!! I had been depleting my glycogen stores completely over the weeks of harder than normal training.
The depletion of carbohydrates from the body can happen over many weeks, and you might not notice it!
If I were you I would forget about your weight for a few days. Eat high-carb food for every meal. Don't limit your intake, just eat a lot of carbs and drink a lot of water. Take a few easy rides, and after each ride, have a sports drink and eat lots of pasta.
After having experienced this fatigue/exhaustiong/loss of power/empty legs a few times during the last couple of years I have started to focus much more on proper intake of carbohydrates. I have to say I am really surprised how much the right amount of carb-intake at the right time has increased my recovery. I am now training harder and longer than I ever have, with incrased recovery, very much due to focus on carbs.
If you try this, please let me know your progresss!
