My killer was the wind. Going down, there was hardly a breeze, so it never played a role. Going home, however, I was against the wind the entire way. Fuck! Slowed me down a lot.
I even had to get off and walk it on the one major up-hill. I just didn't have anything left.
But, I made it. And I'm proud of that. I'm overweight, out of shape, never known a gym to save my life... but I bicycled 10 miles today. That's got to count for something.
