I ride as fast as I can.

Sometimes, I feel good, had lots of sleep or a nice lunch and can ride pretty quick and easy and still feel good when I get to work, not quite as fast as the cars around me, but not much slower.

Other times I am hungover or had a bad lunch (burger or somethin) and cruise a little slower. Still pretty quick in the morning cuz i have to be at work on time, but the afternoon might be pretty sluggish. If I feel really tired I might even cruise on the sidewalk at a jogger's pace..
