Planned to rest most of this week but Wednesday was too nice -- cool but mostly sunny and little wind. Rode 21 miles, which was about all the fun I could stand. My average speed is the same as usual but I still don't have my regular energy. Feeling kinda spent after every ride. Doc says the thyroid meds may take 6-8 weeks to make a discernible difference and it's been 3. I'm anxious to get back to the fitness and energy level I had last March, and am pretty much on target for that.
