Growing up on the west coast of America, Ankrum started racing quarter midgets and later moved up to late models.

[3] Ankrum continues to run super late model races around the country, winning Hickory Motor Speedway's Fall Brawl in 2015[4] and finishing third in the 2018 Rattler 250.

[6] In January 2018, Ankrum signed with David Gilliland Racing for half of the 2018 NASCAR K&N Pro Series East season.

[12] Despite only finishing 13th at the September New Hampshire race, Ankrum left the event with an insurmountable points lead, clinching him the 2018 K&N Pro Series East championship.

[16] When asked in early November 2018 about 2019 plans, Ankrum noted that a lack of sponsorship would likely prevent him from running in the Truck Series full-time in 2019.

[16] However, on December 14, 2018, Ankrum and DGR-Crosley announced that he would run full-time in 2019 starting with the spring Martinsville race due to age restrictions.

[17] At Texas in June, Ankrum graduated high school on a stage during pre-race ceremonies and then recovered from multiple incidents during the race, including a slide down pit road, to finish a career-best third.

[19] He would eventually land a start and park ride with NEMCO Motorsports for races not on his DGR-Crosley schedule, allowing him to remain eligible for the playoffs.

[20] On July 11, 2019, Ankrum scored his first Truck Series win at Kentucky after Brett Moffitt ran out of fuel towards the final lap.
