Absolutely. Walkers are welcome to participate. You will need to maintain a generous pace of 18 minutes per mile to take advantage of the amenities along the course. If you do not keep up with this pace you can continue but will be asked to move to the sidewalks as traffic control will no longer be in place. The course will close on a rolling basis, for example an aid station that is four miles out will begin to shut down one hour and twelve minutes after the start of the race (18 minutes x 4 miles = 1:12).
