After running several races at high altitude, Soratos ran his first sub-4 minute mile in 2015, and went on to emerge as one of the fastest collegiate runners in the United States.

Soratos first attended Hartnell College, where he began training for cross country and track under coach Chris Zepeda.

[4] In his sophomore year at Hartnell, Soratos won four Coast Conference titles and recorded 3:47 at the 2012 California Community College Athletic Association state track and field championships in the 1500 meters,[6] and subsequently transferred to Montana State University at the insisting of MSU coach Lyle Weese, who was once a standout MSU steeplechaser, professional runner, and Hartnell coach.

[7] In one of MSU's home meets, on January 16, 2015, Soratos ran a 4:05 indoor mile, which the NCAA converted to a 3:56 result due to Bozeman's altitude of approximately 4,400 feet above sea level.

[8] However, the following month, Soratos garnered national attention when he ran the indoor mile of at the 2015 University of Washington Huskey Classic, whose venue was much closer to sea level, with a time of 3:55.27.

[11] On the morning of June 25, 2015, Soratos signed with Adidas, and later in the same day ran in the men's 1500 meters of the 2015 USA Outdoor T&F Championships, where he finished 24th overall.
