Shortest way to work 9.7 miles. Charge as fast as possible, or do intervals on the long stretches, or do a moderate 70% pace if its toward the end of the week.
Take a different way home that adds a few little hills I can grind up. Nothing big but its nice to add to the ride. 12.2 miles.
Sometimes I'll head past the house and go the LBS as an excuse to add another 10 miles, buy a gel or two, look at the overpriced stuff I'll never buy from them and then head home.
