kilometers The Great North Run is a 13.1-mile half-marathon (21.08241 km). It is held on or around World Autism Day, which is April 2. The course starts and finishes in Newcastle upon Tyne. However, there are two separate courses: one for men and another for women. They do not intersect but instead each runner must finish by themselves according to a timing system at the end of each course. The total elevation change of the course is about 500 feet from when you start in northern England and travel south into the English Channel. This is equivalent to almost three miles up! The average temperature near the course is 55 degrees Fahrenheit during the day and 35 degrees at night. There is expected to be no rain throughout the run this year except perhaps for a brief shower towards the end. The ground will be dry after the recent snowfall. There are no steep hills but there are several long stretches of muddy terrain due to heavy rainfall last month. The route passes through some major cities including London, Manchester, and Newcastle. There are also some smaller towns along the way. You can expect lots of shops and restaurants along with the usual crowd of spectators.
