Paula Radcliffe's record under threat

The world record set by the reigning queen of British distance running Paula Radcliffe will face an unprecedented threat at today's London Marathon.

She sailed into the record books in 2003 running a time of 2hr 15min 25sec - still the women's world record for the marathon.

But that record is under threat from the Kenyan Olympic team who will use today's marathon as a warm-up, the Mail on Sunday reports.

In particular, Mary Keitany is one to watch. Six months ago she looked set to break the record by the halfway-point in the New York Marathon, only to slow down in the second half.

Given the right conditions, we could see a new record today from Keitany or one of her Kenyan colleagues.
