If you've read Born to Run, you know who Caballo Blanco is, the "White Horse" who went to the Copper Canyons to live among the Tarahumura tribe. Micah True (his real name) was reported missing Wednesday after he didn't return from a run in the Gila National Forest in New Mexico.
He left for solo trail run Tuesday, from the Gila Wilderness Lodge, where he was staying. There is currently a search and rescue operation in effect to find True. You can learn more about the story and get the most recent updates at the blog Flintland.
Hopefully, through the efforts of the greater running community, True will be found quickly. Our thoughts are with his family and loved ones.
***UPDATE 4/1/2012 3:00 P.M.***
The search is over. Micah True was found dead Saturday evening. Rescuers are working to recover the body.
