This year the Simplyhealth Great South Run celebrates 30 years, with thousands of people taking on a 10 mile (16 kilometre) course through the streets of Portsmouth, passing landmarks such as HMS Victory and the Spinnaker Tower. The course is almost flat, with minimal slopes around the course, helping make fast times achievable.
