The Marathon Walk was introduced in 1997 following public demand.
The Marathon Walk is 8 miles long and begins at Belfast City Hall at 9.00am.
It is non-competitive and is designed for ramblers and hikers.
It follows a similar route as the main Marathon Race, the Wheelchair Race and the Team Relay Event.
All walkers must complete the course in less than 6 hours.
The 2018 route will remain the same as the 2017 event route.
