A running event at the Sandringham Estate has been postponed after the death of the Queen.

Run Sandringham was due to take place on Sunday, September 25, but will now be held on Sunday, November 13.

Organisers have said it has been postponed due to the royal estate being in a state of mourning "until further notice".

The 10k race will also take place at an earlier time of 9am.
