Temporary road closures will be in place this weekend due to the Watford Half Marathon.

Runners will take to the streets of Watford and neighbouring villages this Sunday, in an event which has been going strong for 40 years.

The Watford Half will kick off in Cassiobury Park at 10.30am and will follow the same course that has been used since 2015.

During the day, a number of roads will be closed for the safety of participants. Take a look below to see if you will be affected and where should be avoided.

The first time is when the road closes and the second is when the road will be open again.
