I blogged earlier in the Olympic Games about how bad the commentary and coverages was of the cycling – http://www.v1seo.co.uk/11/bbc-coverage-of-the-cycling-what-a-joke/ but having just watched the 50km I think the bad commentary has been surpassed.
If they were giving out gold medals for bad commentary it would have to go to the commentators of the 50km walk.
