Searchers found Colorado barefoot ultra-runner Micah True’s body  in the remote New Mexico wilderness on Saturday. He had gone for a run near the Gila National Forest on Tuesday and disappeared. The Boulder (Co.) Daily Camera reported that “the cause of death is unknown at this point. There were no obvious signs of trauma.”

True was known as “Caballo Blanco” and garnered worldwide fame in the 2009 best-seller “Born to Run.”  He had  a Twitter account and this was his last Tweet:!/mcaballoblanco/status/184459020952813568
