Tyler Pennel

Collegiate Pennel stayed in Colorado and committed to Western State College where he won an individual national title, a team national title, and was an 11-time All-American. His individual title was his first place finish in the men's 10,000 meters at the 2012 NCAA DII Outdoor T&F Championships. At Western State, Pennel trained almost always at an altitude higher than 4,000 feet. He then competed at the 2014 IAAF World Half Marathon Championships where he finished 33rd. On June 4, 2015, Pennel ran his first sub-four minute mile at the Festival of Miles in St. Louis, where he finished second in 3:58.99.

In 2016, Pennel competed in the Olympic Marathon Trials which doubled as the USA Marathon Championships in Los Angeles where he finished 5th in 2:14:57.

Pennel planned to compete in the 5000m and 10000m trials for the 2016 Olympics but a stress fracture in April ended his Olympic plans.

In his first 2016 race back from injury, he finished 8th in the 2016 NYC Marathon, with a time of 2:15:09. He was the third American man across the finish line.
