I have been riding with frequency that does not reflect my online handle, on the road 3-4 days a week doing 25-40 mile rides each time. These rides are usually quite fast, at around 20+ mph with a group (or 17-18 mph solo), with faster bursts. I guess I could say that I'm doing 80-100 miles a week.

Which doesn't sound like much to most of you, I'm sure. But lately, my legs have been feeling heavy and my last ride felt "flat", without a ton of energy. I'm not that tired, but there doesn't seem to be enough spring or bounce in my legs. I was supposed to ride this morning, but I didn't go because I didn't feel like it.

Is this a sign of overtraining? I wonder because I really don't ride THAT much, but when I ride, I ride intense.
