To my understanding, the reason under IAAF rules that his attempt will not qualify as a WR is because he has special place setters and rabbits. Uh......ok? All marathons and track races have pace setters and uncover rabbits.
The fact is......unless this marathon in vienna has an extremely downhill gradient, same as a 100 meter race that has a big tailwind, unless that is the case, then this should absolutely qualify as an official world record for him. Period.
