I have a shade over 7 miles to work. I get my lunch together the night before and make sure the battery is charged for my headlight. I leave at 4:15 am so its dark no matter what time of the year I'm riding. I always have an extra shirt packed in the panniers and I have two tubes and a patch kit also air pump +1 on the topeak road morph. I have an assortment of tools, couple of screwdrivers and metric wrenchs and a set of allen wrenches and also a multi tool in the panniers and a seat bag. In the morning all I need to do is grab the lunch out of the fridge get the bike out of the garage pack the lunch in the other pannier and off I got takes me about 30 minutes. Oh yeah I have a small first aid kit and some latex gloves in case I have to change a tire and a small garbage bag just in case I might need it for whatever it might come in handy for.
