The Routes
Each of the three routes (Half Marathon, Full Marathon and 50Km Ultra) start from the Pyramids Centre in Southsea. Starting and finishing in the same place, all of the ‘out and back’ courses can best be described as “multi-terrain” with a mixture of paved promenades, gravel coastal paths and even some sections along the beach (on Hayling Island). All courses offer incredible views of the Solent, historic naval sites and local wildlife habitats. Because the terrain varies, runners experience both fast / flat stretches and more challenging trail segments, making it a uniquely balanced and engaging race.
