The 5K starts at the same time and place as the half marathon! You'll run (or walk) the same course as the half marathon up to Mile 2.5, at which point you'll veer right when the marathoners stay straight. The course then goes up a short steep hill (sorry!) but finishes with a downhill stretch through the heart of downtown with thousands of cheering spectators!
