You will have to play in matchmaking matches and it doesn't matter where you finish, just finish the race.
You can play only with the CPU or with human players (it's your decision).
NOTE: If a CPU or human player reached the finish line first, you will only have 10 seconds to finish the race.
If time runs out and I don't make it to the finish line, then it will be considered a lost race and will not count towards the achievement.
It also doesn't matter if he finished last.
This achievement could take more than 4 hours.
