Hidden cameras, criminal background checks, and nearly two weeks of surveillance. This story has it all. They found that Rupp regularly uses a house owned by the Salazar family to start many of his runs to the Nike campus. And he uses the underwater treadmill in the back.

From Salazar using the LetsRun messageboard to guide his 2011 Boston Marathon coaching to a drunken attempted kiss of Kara Goucher on the plane to the 2011 Worlds to Salazar crediting Chris Solinsky's 26:59 to Solinsky being on thyroid med, Matt Hart's fantastic new book has some fantastic revelations.

Alan Webb, Dathan Ritzenhein and Ryan Hall had never sat down and talked about their careers until this week. Find out why Ritz had Webb's face on his dartboard as a high schooler, how Webb was able to beat Ritzenhein in their famous 10k showdown in 2006, which performances each believes was the best from their careers, their biggest lessons from the sport, their views on new shoe technology, Webb and Ritz's thoughts on their time with the Nike Oregon Project and Alberto Salazar's ban, and much more.

Nike has issued a statement saying they will start an immediate investigation of the "troubling allegations" while Cain has confirmed she did try to rejoin the team in April of this year. Additionally, three former NOP members have said Salazar was very focused on the weight of his female athletes, but Salazar has issued a forceful denial of Cain's allegations, writing to Ken Goe, "To be clear, I never encouraged her, or worse yet, shamed her, to maintain an unhealthy weight.”

Among other things, Cain says she became suicidal while she was part of the NOP and says when she told Alberto Salazar and Darren Treasure that she was cutting herself that "they pretty much told me that they just wanted to go to bed."

The mile in Boston was pure insanity. Kejelcha finally got the WR after three tries (but missed the 1500 en-route) as Gregorek ran 3:49 and Sam Prakel ran 3:50.

Has Alberto Salazar lost his mind or is it smart for Kejelcha to try to get two WRs in one race?

Are you ready for a WR in the men's mile? You probably should be.

Goucher reveals that he thinks a resolution is looming soon in the Nike Oregon Project doping case. "I think it’s coming very, very soon, but until there is that ultimate resolution, you’re just kind of waiting."

This morning Matthew Centrowitz revealed exclusively to LetsRun.com that he has left the Nike Oregon Project.

Six years ago, they were training partners, the best of buds and on top of the world after going 1-2 in the 10k at the Olympics. Now they are rivals, and this Sunday in Chicago, Mo Farah and Galen Rupp will be quare off for the first time at the 26.2 mile distance.

Jordan Hasay is back at Chicago as well after her third place 2:20:57 run last year.
