THE London Marathon is extraordinary. We are condemned as a nation of obese coach potatoes, yet on Sunday 10,000 people will run 26 miles.

We are dismissed as the self-obsessed society, yet almost all those competitors, including York Professor Sally Baldwin's daughter Julia, will be raising money as a tribute to a loved one or friend.

The only sour note comes from Gordon Brown. Despite protests, he is set to skim £3 million of donations for the Treasury.

The Chancellor had better keep away from London this weekend. Otherwise he may find himself pursued by thousands of fit and furious fun runners.
