There's a certain piece of road. Every time I drive along it, the 
monitor tells me my heart rate has hit 700 BPM. I'm fairly sure that's 
physiologically impossible. ;-)

Walking just feels like I'm not achieving anything. I mean, my legs feel 
crippled after half an hour or so, but my heart rate has barely moved 
from when I'm sitting down, and I don't feel particularly tired. It's 
just that my calves hurt.

Gotta mix it up to stave off the boredom. ;-) Besides, now I can delude 
myself that my arms look more muscular. (Even though that's obviously 
impossible after a mere 20 days...)

If I could actually run for an hour straight and not *die*, that would 
be quite impressive...
