BOISE, Idaho (AP) -- The first time Shane Niemeyer thought about Ironman triathlons, he had just tried to hang himself.
It was 2003 and he was a 27-year-old homeless heroin addict in an Idaho jail, awaiting sentencing for drug possession and burglary. Guards put him in a straitjacket, so he says he used his feet to turn the pages of the magazine article about the endurance sport.
There was something about triathlons - and the commitment they demanded - that tripped a switch inside him: Maybe this was his way out, Niemeyer thought. Maybe he could spend his days swimming, cycling and running, instead of beating up Honduran drug dealers or burglarizing businesses to fuel his habit.
"I read the distances," said Niemeyer, now 35. "I read the average time triathletes spend training. It was overwhelming to me. For some reason, I figured that would help occupy my time."
Since his March 2004 release from a prison drug program, he's done eight Ironman distance races, covering a combined 140.6 miles in each. He placed 19th at a 2009 Ironman race in Wisconsin, out of nearly 2,400 competitors. On Oct. 8, Niemeyer finished his first Ironman World Championship race in Kona, Hawaii.
But Kona, a race many count among the world's toughest sporting events, wasn't his biggest accomplishment of 2010.
