I think I set a record today.
For my slowest ride all season. 
Today, I intended to do a "brick" - ride to/from work. Come home, throw on the sneakers and head out for a 2 mile run around the neighborhood. Perhaps my last chance to run before Friday's 5K and Sunday's 8K.
But as I started riding in this morning, my legs were telling me that they had other plans in mind. Like, the left hamstring was singing a lot...and the right quad - which I pulled at the gym last Wednesday - was singing in harmony. Coming home, I stayed in the small ring to try to spin-spin-spin-to-win, but the legs just had no power. No pepper. No umph. And that quad kept singing along - quite out of key I might add. 
Used the TENS on the leg this evening. Might do it one more time before I hit the sack. I may try my brick again tomorrow. We'll see what my legs say about the matter.
