It may sound silly...

...but you've got to run quite a way to run 7 miles. Certainly around here anyway where there are no obvious long routes - you end up weaving in and out all over the show! it's a job remebering where you're going! Still, the future Olympic site was succesfully circumnavigated (with a few little extra bits it came to the required 'slow' 7M) in 55:02.
