"The average kid doesn't want to break a record. We've been buying him those Guinness books since he was 3," Taylor said. "He's never wanted to quit. It took four and a half years to get the half marathon record and never once did he want to stop."
At first, Jaquez only wanted to run half-marathons in all 50 states. But that goal changed when he learned he could break the record.
He's now run 55 half marathons – two in Illinois, two in Texas, two in Florida – and one in Iceland.
"He asked if he could go to Iceland and I said 'why Iceland,'" Taylor said, "and he said 'because I want to save the puffins [birds].'"
He's had his share of experiences along the trails.
In Rolla, Missouri, Jaquez started a race in 68-degree weather, and took his sweatshirt off. By the time he finished, it was 39 degrees and raining.
In Oregon, the first half-mile of a race was across the Bridge of the Gods, a 1,858-foot-long cantilever bridge suspended 100 feet in the air.
"I ran as fast as I could across that bridge," Jaquez said.
