Yet it is not a world record. Why? The explanation is pretty logical, actually, and it turns out "have the wind" at your back isn't the best advice in such matters.
Because Boston features more downhills than uphills and is a point-to-point Marathon course rather than a loop, it is not eligible for marathon records.
Further, a course that is point to point can have its times significantly affected by tailwinds, which is exactly what happened today.
The first four finishers -- including American Ryan Hall (2:04:58) -- surpassed the course record of 2:05:52 set last year by Kenya's Robert Kiprono Cheruiyot.
There are no wind or elevation advantages on a loop course, which is why the world record of 2:03:59 set by Ethiopian Haile Gebrselassie in Berlin in 2008 still officially stands.
Mutai has no complaints, however. He picked up $150,000 for winning the race, and the Boston Athletic Association will pay him another $75,000 for his course record and "world-best" performance.
