Here's a new endurance race for 2012. The wall Run starts at carlisle Castle and ends at Gateshead Millenium Bridge. The 69 mile route follows the course of Hadrian's Wall, which marked the Northern-most boundry of the ancient Roman empire.
The race is held over two days 23rd & 24th June, although those wanting a more serious challenge can run the route in one continous outing.
