All the races within the Swansea Bay 5K series start and finish at the Blackpill Lido, right in front of the Junction Cafe Bar.
The course follows virtually the same route as the middle half of the Swansea 10k.
The image shows you the out-and-back route taken by the race, click on the image for a more detailed view. As you can see the course is straight and flat, all of it running along the sea front. The turn around point is right in the middle of Mumbles.
Click here for a map showing the start (the marker is slightly to the left of the lido). The lovely people at Google will even let you put in your home postcode and provide you with driving instructions. If you look at the satellite image you will see that there is a car park just north of the start area off Derwen Fawr road.
