text: Very interesting.  Maybe we should start testing Mt Marathon participants who finish in the Top 10. Doping is used if you can get away with it.  Always wondered about some of these other Alaska races. Do we drug test Iron Dog racers and Marathon runners.. If folks are cheating we need to know so lets not just pick on the prestigious Iditarod.  Some of these "legends of their sports" are outside the realm of drug testing and have done very well thanks to the local doctor I suspect.
