For the fan Festival and TrackTown24 specific branding, the number 8 played a suttle underlying role, as it was the 8th time that the Trials have been held at Hayward.  The main 'pinwheel' mark has 8 towers and is a nod as well to the original pinwheel logo of the 1972 Trials.  The number 8 is also hidden in the main wordmark.  For a consistent border, the silhouette of the current stadium is used.
