The race starts and finishes at Ormeau Park, the oldest municipal park in Belfast and still one of the largest parks in Belfast. The route is an incredible tour of the capital City, soaking in cultural landmarks like the towering Harland and Wolff Cranes, the vibrant Custom House Square, and the majestic City Hall.

Road closures will be in place across the city to safely facilitate the race so motorists are advised to expect disruption throughout the morning.

Motorists are asked to follow diversion signs and take direction from stewards on the route.

The front runners are expected to pass over the Sam Thompson Bridge onto Airport Road at approximately 9.35am and make their way to Queens Square at approximately 9.40am via Sydenham Road and the Lagan Weir Pedestrian Bridge. The runners are anticipated to pass through the city centre from Custom House Square, via High Street, Cornmarket, Arthur Street, Chichester Street, Castle Street enroute to the Falls Road at approximately 9.50am.
