Ridiculously good

No, not the latest creation from Shenandoah Joe's bakery. But the sensations in my legs, lungs, and body when I ride a bike.
I mean, really. I have no idea where it came from. My only guess is the Lay's Potato Chips. Classic flavor, of course. Only the best for my long-femured little gams.
I trained maybe 10 times in the past 4 weeks. I ate indulgent "on the road" food in my recent trips. I am exhausted beyond the point of exhaustion and back around again.
Yet I feel ridiculously good when I ride a bike.
Have I elevated my heart rate above Zone 4? No. But have I effortlessly spun up hills that for the past 2 years have left me s-c-r-e-w-e-d? Yes.
What gives?
El Gato, in his infinite wisdom (no sarcasm: homeboy earned this knowlege!) believes that it's because I'm in a good place mentally. I love school (until I have to analyze ROE for 6 different businesses in one night plus do two other cases). I had the break I needed from racing (I showed my license 3 times in 2008). That I'm finally under 125 for the first time in a year and a half. That I am old (read: over 30) and entering my endurance athlete prime as a woman.
I'll take that.
Not sure what I'll do with this ridiculous "feeling" (because it sure ain't fitness). But I'll take it nonetheless.
