Thousands of supporters and spectators expected to line the streets cheering on the competitors.
Organisers have set up spectator points to ensure people can get a good view of the spectacular event.
The marathon starts and finishes at the University of York’s Heslington campus. Its route travels through the historic city centre – passing through the medieval walls – and takes runners north eastwards out of the city.
A number of routes will be sealed off to allow the event to go ahead. More details can be found at www.theyorkshiremarathon.com/news
