You're hardly going to walk into them during a normal visit to the dockyard, but when there are hundreds of runners around you they become an unexpected challenge. | Other 3rd Party Photo: Mary Turner
6. If you want to be near the front, arrive early. Really early.

7. The joy of the jelly babies when you get near the end
They are usually handed out with about a mile to go, and you'll see lots of runners near you with a handful of them - hoping for that last-minute sugar rush. | JPIMedia Photo: Chris Moorhouse
8. The warm-up may look silly - but it really helps
Yes, you might look a bit odd. Yes, you might be wondering what the point of it is. But believe us, once you've got through the whole 10 miles you'll be glad you did it. | JPIMedia Resell Photo: Chris Moorhouse
