CONCORD, N.C. – Earlier this week, the first round of the Hendrick Motorsports Pit Crew Playoffs – presented by Valvoline – wrapped up.

The ongoing competition tests the athletes’ skill, agility and determination – and perhaps a bit of luck is involved along the way.

The athletes were pitted in one-on-one matchups in a series of games including the lugnut stack, marshmallow challenge and cookie face race.

Check out every one of the games below now that the 16 athletes have been trimmed down to eight quarterfinalists.
