Boston Marathon 2010

With the recent problems on air travel that would be a hazard for air passengers since the volcanic eruption on Iceland that spewed ash, some of the top contenders for the upcoming Boston Marathon 2010 have already withdrawn from the event.  Even John Hancock himself, who is one of the main sponsors for the Boston Marathon has already announced his upcoming absense to the event because of rescheduled flights.

European contenders were greatly affected by the ashfall
