Duh.
BUT then I read that if you bike slow(ish) for forty minutes with bursts of speed every few minutes then you will lose the most weight.
How interesting...
So I tried that.
And apparently biking in spurts of speed on a beach bike on a windy, bumpy, root-covered trail breaks your bike.
Oops. I guess that's my own fault entirely and I should have seen it coming.
The chain came off my bike and I was headed down a very narrow, wiggly path without brakes. I dragged my feet (drug my feet? drigged my feet? honestly...) until I stopped.
Then, while listening to Iron and Wine, and wearing a white skirt, and being in the middle of a state park (aka in the woods), I PUT THE CHAIN BACK ON MY BIKE.
It was really hard, and I had to say a little prayer after the first unsuccessful ten minutes.
But I am impressed with myself, and you should also be impressed.
I tried to wash my hands in a puddle.
Then I tried to wipe them off on leaves.
Then I biked home, and took pictures of my blackened fingers.
