The feature-length documentary follows the life of Micah True, aka Caballo Blanco, an ultramarathon runner made famous in Christopher McDougall’s bestselling book Born to Run.
The film explores how True first started running and details his efforts to aid the Tarahumara community by founding the Copper Canyon Ultramarathon in Mexico in 2003, according to Runner’s World. True died on March 27, 2012, while running in New Mexico. The race was renamed the Ultramaratón Caballo Blanco after his death.
