Revealed: The Leeds roads facing 12-hour closures when the ITU World Triathlon Series comes to the city in June

The race itself will consist of three main elements, which will see the competitors travel through Roundhay, Moortown, Meanwood, Weetwood, Headingley and Woodhouse and parts of the city centre.

The world’s top triathletes will take on a 1,500metre swim before a 42.5km bike ride and finally a 10km run finishing in Millennium Square.

Race organisers have revealed that the scale of the event will mean roads around the route are expected to close and be clear of vehicles on June 12 by 5am at the latest.

Those roads will be closed for a minimum of 12 hours although emergency access for ambulances, health care providers and other agencies will remain.

All affected properties are receiving the first of two letters with early details and guidance from today.
