It is rumoured that Bekele wants a 2'55/km opening pace (http://www.vo2.fr/actualite/marathon-marathon-de-paris-2014-04042014-8696.html). It would be world record pace but for the very slightly downhill in the first few kilometres.
Despite of having a better 10K shape at the time (Bekele is now far from his peak), Haile had a "difficult" 2:06 debut in London.
So nothing is done uet and you'll be watching nervously. I'll be hobby jogging another marathon around the same time so I'll learn the results afterward.
