If he breaks his own record does he again get 100 million yen?
From Letsrun.com race preview:
It will be interesting to see how aggressive those guys are; remember, there is still a 100-million yen ($900,000) national record bonus from Project Exceed on the line, though the record is 26 seconds faster than it was this time a year ago. Osako, who already claimed the bonus in Chicago last year, may need to break the record again if he is to win the race. Though the temperature will be ideal for marathoning (high of 48 on Sunday) and there isn’t much wind in the forecast (6 mph), Weather.com predicts a 100% chance of rain on Sunday.
