Eldoret (Kenya), April 15 (IANS): Berlin Marathon silver medallist Emmanuel Mutai said he will wait to see whether to race at the Beijing World Championships after he rates himself against the best at the London Marathon on April 26.

"After running in London, I will see if I have the energy to go for it in Beijing. It is a little bit closer to each other and it requires special training. My plan was to run in Tokyo, then Beijing, but the allure of London was too good to ignore. Now I have to plan afresh," Mutai said on Tuesday, reports Xinhua.

At 30, most athletes consider venturing into marathons but for Mutai it is like he has been here for eternity, having run his debut 42 km race in 2007 in Rotterdam.

"Time in London is not an issue. This is because of the high calibre of opposition on parade. I have my plans and done my training well but I have no idea what calibre of challenge to expect in London," said the Kenyan.

The challenge includes world marathon record holder Dennis Kimetto and New York Marathon champion Wilson Kipsang, who broke Mutai's London course record last year.

In 2011, Mutai won the London race with a course record of 2:04:40. But Kipsang, who set the former world record of 2:03:23 at the 2013 Berlin Marathon, broke the London course record last year when he won in 2:04:29.
