The Tennessee Knockout had nearly 400 entries for 2019 and the amateur riders competed in a Friday prologue and had two races on Saturday. The top 30 amateur riders earned the opportunity to compete with the 27 pre-qualified pro riders on Sunday. Sunday includes a Hot Lap to set starting positions. Then the first Knockout round, on a 19-mile course, cuts the field of riders down to 25 and an LCQ earns a final transfer spot for one additional rider. Those remaining 26 riders compete for the final 15 spots in the main event with another loop on the 19-mile course with some more difficult sections added. The main event is a 30-minute plus one lap battle on a mile-long short course.
