MX vs. ATV: Untamed

Be the first bike to the first corner in a Supercross race and you win the holeshot. This is marked by two black-padded poles with red lights on top. You can look at the results to see if you won any holeshots during the race. Accumulate 10 and you get the achievement.

Set up a supercross on any level with 1 lap and only 1 player then you will get it every time, and just keep repeating untill you have 10 and bang, you get the achievement.
