Kenijas skrējējs Mutai Bostonā sasniedz neoficiālo pasaules rekordu maratonā

Kenya's Geoffrey Mutai ran the fastest marathon ever on Monday, finishing the Boston Marathon in 2 hours, 3 minutes, 2 seconds. Despite the blistering time, Mutai's mark isn't being recognized as a world record. Why not? Even though it's considered one of the most challenging marathon courses in the world, the Boston Marathon is run on a net downhill, making it ineligible for world records. USA Track and Field only recognizes courses that meet specific criteria about elevation changes as record-eligible. Those courses must drop less than one meter per kilometer to fit the standard.
