My biggest issue with this attempt is that it is against the spirit of running.
Running is supposed to be about the runner, his talent, training and effort. Other sports depend on skill, money, funding, specialized coaches. Running on the otherhand is a much more level playing field, a true measure of one's ability and hard work against another. That's why some of our biggest heroes came from nothing to stardom, like Geb or Bikila, etc. etc.
Now, I am afraid all that will matter is who has the biggest sponsor to pull off a stunt like this. You ran a 2:05 on your own with minimal support? Well now you suck compared to the 25 guys who ran 2:02 or faster thanks to sponsored "stunts" by Nike, Adidas, NB, Asics and anyone else who wants to jump on the bandwagon.
And who's to say this trend won't continue in every single attempt? The 10K? 5K? 1 mile? Sure, they have professional pacers in Diamond League and whatnot but certainly not a phalanx of pacers who can swap in and out. Those races also arent championships so nobody trains for an entire season or "peaks" for that event skipping out on other racing opportunities because they can't afford it.
Imagine if Nike gave Kiprop a million dollars to take 6 months to focus on a record breaking event. It would become a circus.
