You're the best around!G 50

This achievement is also quite easy to unlock and will be yours before you finish off all the St. Lucia DLC. You will need to complete 100 Bronze, 75 Silver, 50 Gold, and 25 Platinum trials for some other achievements. As you complete these trials you will earn points. The harder the trial and higher level medal you play the more points you will receive. You can also replay the same trails which adds a multiplier (Milestones) to the base points you would receive.

If you want to quickly pop this achievement simply find an easy 10,000 point trail in the player uploaded trial list and replay it. I was able to unlock the achievement before hitting 150/250 completed trials that are needed for some of the other achievements so there is no reason to fret, it will pop naturally as you play though the trials.
