Well, I'm sitting at home right now (when I would normally be at work), so it was not a great morning. However, it may not be as bad as I'd feared (hoping).
I started off riding as normal. Felt fine, even though I slept poorly last night. Developed a sudden, sharp localized pain on the back of my left thigh. Fearing a hamstring injury, I turned around and headed back to home.
That's the bad news.
The good news... after some checking, it looks like some kind of bee sting or spider bite... which I will sooooo take over a hamstring injury.
So today, I'll have to ride vicariously through the rest of you.
