More than 3,000 people are expected to take part in a run through the streets of Dublin today.

The Lord Mayor will lead the way for the five mile route this afternoon, starting in Raheny at 3pm.

The 31st annual event is part of the 5Alive challenge - which is a series of short runs designed to help people get fit for the new year.

Organisers say there is limited car parking available and to use public transport.

The route begins on All Saints Park, proceeding to All Saints Drive, Watermill Road, Howth Road, Sybil Hill, Vernon Avenue, Mount Prospect Avenue, Seafront (at Wongs), Watermill Road, All Saints Drive, Wades Avenue and finishing on All Saints Park.

The AA says there will be rolling road closures in place, while a large crowd is expected to gather around Raheny Village from 2pm.

Some Dublin bus routes will also be affected for a short period of time.

Lord Mayor Christy Burke is confident there will be a good turnout.
