Geoffrey Kiprono Mutai is a Kenyan long distance runner who specialises in road running competitions. On 18 April 2011 at the Boston Marathon, Mutai ran the fastest marathon ever at the time in a time of 2 hours 3 minutes 2 seconds, though the time was not recognised by the International Association of Athletics Federations as a world record since the Boston course does not meet the criteria to be eligible for the mark.
