Well, the Idiot-rod used to be a fun race until folks started to take it seriously. I remember Mary Shields ran it, Red Olson kind of bird dogged her, then let her finish ahead of him so she wouldn't get the red lantern. (Red donated the burl logs for the finish line.) Then Mary turned around and mushed her dogs back 'cause she didn't have the money to fly them out of Nome. When was that, 1975 IIRC? Bob Schlentner completed the race with 5 dogs, and I believe he was the only one who has done that. Back then you had to start with seven and finish with five. Probably half the mushers carried all of their gear and dog food from the start, with no food drops at the check points. George Attla thought he could win it in ten days with his sprint team. I don't think he ever finished....
You have to remember though, that when Redington got the Iditarod going the races had become all sprints and there were no long distance races. When it became so commercial the Quest was started to have a fun race again. And if the qualifications for the Idiot-rod hadn't added the requirement of running another long distance race, some of the others probably wouldn't be around.
