I work up here during the week and rent a room in Concord. I have been riding to the office when I can. I have to drive to other locations for the customer a few times a week. I stay over the weekend every other week or so and that is when I can work on the bikes. There is the Iron Horse trail nearby and the Contra Costa Canal Trail that I have been riding on. I rode up to and around the town of Clayton a couple of weeks ago and there were a few good hills on that ride.
