Summarize Timeline Top Qs Fact Check

Kessler competed for Skyline High School in Ann Arbor, Michigan, as the high school he attended for academics, Community High School, did not offer competitive sports. During Kessler's senior year, his father was the high school track coach. However, wanting to keep a non-professional relationship with his son, he had the renowned University of Michigan coach Ron Warhurst plan most of Hobbs' training. This allowed Hobbs to train with professional runners Nick Willis and Mason Ferlic for harder workouts while still allowing him to do easier efforts with his high school teammates.

In September 2020, Hobbs committed to compete at Northern Arizona University.^[3]

On February 7, 2021, Kessler broke the U.S. high school indoor mile record by running 3:57.66 at the Randal Tyson Track Center where he placed third in the race.
