Carmichael is not "under lawsuit" for anything. Armstrong merely and by his own admission, "told Chris Carmichael in 1995 of his use of P.E.D.s."

I have noticed several publications and websites recently writing articles about the plague of doping (PED usage) coming to the niche of ultra marathon running where popularity, prize purses and sponsorships are growing but drug testing is minimal to non-existent.
I have also noticed that with this increase in purses and sponsorships that groups of ill-repute like Carmichael Training Systems (founded and run my Lance Armstrong's long time coach Chris Carmichael who is under lawsuit for having doped heavily former athletes under him), has moved strongly into the world of ultra running lead by Chris's Director of Coaching Jason Koop. Koop has taken on multiple top ultra runner's in recent years.
The fact that groups like CTS have branched from the world of cycling into lesser tested sports like ultra running should concern any who love the sport.
That is a very different thing.
