31 hilly miles RT twice a week on Tues and Thurs. I can't do Monday or Wednesday due to my wife's schedule, and I don't want to ride Friday because I haul all my week's crap home that day. I usually do the round trip in about 2:20 to 2:30 total. With the time change I'm starting to leave the house about 6 AM so I can get in early, then leave about 4:30 so I have a bit of light left to start out, and get home before 6 PM.
