The TKO is the creation of Dan Brown, the owner of the Trials Training Center, with Eric Peronnard, the founder of EnduroCross. The first race was on 28 August 2011. More than 50 riders entered. Tennessee's Mike Brown won on a KTM ahead of Cody Webb and Canada's Bobby Prochnau. Brown won again in 2012, with Webb second again.

Webb's six in a row. Webb won every year from 2013 to 2018. He won on a Beta in 2013 and 2014, then on a KTM from 2015. In 2015 he beat Jonny Walker by 1:43. In 2016 he lapped the whole field. In 2017 he held off Graham Jarvis. In 2018 he beat Manuel Lettenbichler, who was racing his first TKO.

The first international winner. An injury kept Webb out in 2019. Lettenbichler won on a KTM 300 XCW TPI, ahead of Mario Román and Wade Young.

2020. The TKO was due to be round 6 of the WESS Enduro World Championship. In June 2020 it was withdrawn from WESS because of COVID-19 travel limits. The race still ran in August. Trystan Hart won all four rounds and beat Webb by just over 35 seconds.

World championship years. In 2021 the race became the Red Bull Tennessee Knockout and a round of the FIM Hard Enduro World Championship. Billy Bolt won by 2 seconds from Lettenbichler, in his first race in the US. In 2022 Hart won again. It was his first world championship win. In 2023 Hart won for the third time, less than half a minute ahead of Bolt. In 2024 the TKO was back in the world championship, and the weekend started with a prologue on Broadway in downtown Nashville. Lettenbichler beat Hart for his second TKO win.

Lettenbichler's run. Lettenbichler won again in 2025 and 2026. Hart was second all three years.
