Video of the 2008 Cork BHAA 'Grandons' 5 Mile Road Race...
I found this video clip on my travels around the Internet ;o)
It shows the start of the Cork BHAA 'Grandons' 5 mile road race in June 2008 out around the half mile mark, just as the field begins to thin out. The clip is about 4 minutes long.

(You will probably need broadband to watch this video)
