All-weather covered bike paths and open outdoor bike paths provide a healthy option for commuters and such activities are facilitated throughout Circle City. In Winter the Mall may serve as an indoor bikeway. Lightly covered bike paths serve for the rest of the year, and many of the pedestrian wallkways will serve a dual purpose for biking, blading, jogging, or other mode of travelling about. Underground tunnels are provided throughout the residential districts and in the business districts for commuter access.
