They say that truth is stranger than fiction. The more pressing question is how to distinguish between the two.

Narratives are easily created – it is my stock in trade, and the trade which every sports writer plies – but where does stringing together a collection of related facts move from being a factual reconstruction into the realms of invented fantasy?

When different individuals view the same facts and draw radically opposite conclusions, are we to believe that one is delusional and the other is sane and objective?

Most of all, how much value should we attach to the opinions of each side? Do we change our opinion of the facts based on our sympathy or antipathy for the messenger?

That is the confusion which the final round of MotoGP has thrust the world of Grand Prix racing into. What should have been a celebration of the greatest season of racing in the premier class in recent years, and possibly ever, was rendered farcical, as two competing interpretations of a single set of facts clashed, exploded, then dragged the series down into the abyss.

Bitterness, anger, suspicion, fear, all of these overshadowed some astonishing performances, by both winners and losers. Looked at impartially, the Valencia round of MotoGP was a great day of fantastic racing. But who now can look at it impartially?
