Yulara, Australia; July 25
Experience the Northern Territory in a truly unique way: by running across it. This marathon also offers three shorter-distance options, all of which cross bush roads with stellar views of Uluru, the famous Aboriginal sandstone formation, and Kata Tjuta, the area’s landmark red-rock domes. The marathon’s coordinators can arrange for travel packages (from $855) that include up to five nights of lodging and guided outings, or book a trip with Marathon Tours, and it’ll do all the planning for you. Add extra days to explore the cultural highlights of Uluru–Kata Tjuta National Park, and book tickets (from $43) to Field of Light Uluru, an outdoor art installation across the desert that spans a distance equal to seven football fields.
