Following the challenge, Johnson stated, "In this discipline, the athleticism and training really pays off. We made a big effort to get full-fledged athletes who did nothing but work on their pit stops and disciplines. And then they focused on this — the distance to run, the car push and all that — and I think it just shows how strong they are, how physically able they are to get the job done." In addition, the event had individual winners who were the best in each category: jack man, gas man, front tire changers, and rear tire changers with the addition of two tire carriers. The jack man competition was won by Jeff Keer, from Kasey Kahne's Hendrick Motorsports' No. 5 team, while the gas man competition was won by Tom Lampe, who was from Kyle Busch's Joe Gibbs Racing No. 18 team.
