Mary Keitany to defend London Marathon title
Defending women's champion Mary Keitany will lead a quartet from Kenya at the 2012 London Marathon.
The 30-year-old will face a tough battle against her compatriots, including world champion Edna Kiplagat, Paris winner Priscah Jeptoo and Berlin victor Florence Kiplagat.
"This has to be one of the most talented women's fields we've ever had," said race director Dave Bedford.
"With Olympic places up for grabs I'm sure we'll see a fantastic race."
There will be one remaining British women's marathon place up for grabs after world record holder Paula Radcliffe and Mara Yamauchi secured the other two Olympic spots.
"With the Games in London just a few months later, the incentive for British marathon runners couldn't be greater," added Bedford.
