The Sheffield Half Marathon takes place on Sunday (April 14), with more than 7,000 people expected to take part.
Thousands more will be lining the streets to cheer them on, meaning the city will get very busy very quickly.
For those travelling by car, finding somewhere to park will be important.
There are a number of places around the city that will be available to use.
Here is a list of the car parks, along with the post codes you will need to put into your sat nav in order to find them.
All are within walking distance of the starting line on Arundel Gate in the city centre.
However, there are bus links and the tram if walking is not an option.
