I try to take a different route every time I go to or from work. It keeps things less boring. The theme for tonight's ride home is to criss-cross Highway 85 a ridiculous number of times (9 times to be exact). Here's the route (ridden south to north this time):
So the other thing I sometimes do to spice up the commute is "interval" work once I reach Foothill. I put "interval" in quotes because I don't do it scientifically or methodically. More like "ride really hard up this false flat section" and then "take it easy for a while once I've made it through the yellow light".
Any other games that you all play other than the usual dodging of cars?
