I ride my bike.
Yesterday I missed the bus to go back to campus in the afternoon. I had to drop off a lab report and get to class in twenty minutes. That's not a terrible proposition. All down hill from here to campus, I thought I'd have time to spare.
Unfortunately, the building where I have lab is down the hill from my class. Ok, I was like two minutes late to class, that's not too bad. I don't take that class particularly seriously.
All the BT busses have bike racks on the front, so you can theoretically ride your bike down the hill and take the bus back (or vice versa if you live downhill from campus). I was in no rush to be anywhere though, so I figured I'd just ride home. Bad Idea™. In low gear up the hill, I took nearly half an hour to get home. I thought I was going to die. I am so out of shape.
I woke up this morning and my chest and legs are still sore. I'm still trying to figure out why my chest is sore.
