Challenge Mode

1. Participation Award - Must be earned on your own. Only the main challenge counts, not the sub-challenges.
2. Second (the) Best - Must be earned on your own. Only the main challenge counts, not the sub-challenges.
3. Golden Boy - Must be earned on your own. Only the main challenge counts, not the sub-challenges.
4. I Make This Look Good - Must be earned on your own. Only the main challenge counts, not the sub-challenges. Buy a skin and a bike decal and equip both; even if the Challenge doesn't utilize the bike, it will still count.
5. Worthy - Upgrade the Gear skill.
6. Lost & Damned - Get a Bronze on any sub-challenge. An easy one is Reload--just shoot the barrel at the start. Please note, for some reason Mediafire doesn't like this file so in order to get it to upload I had to add a miscellaneous dummy text file. You'll have to unzip, delete the text file, and re-zip before resigning.
7. Dolla Dolla Bills, Y'all - Buy a skin or decal.
8. You Done Good, Kid, Gotta Patch 'Em All & Gold Team Rules - Get 5 seconds of air time for You Done Good, Kid, finish the challenge with a Bronze for Gotta Patch 'Em All, and finish the challenge with a Gold for Gold Team Rules. Here's a guide if you're having trouble. This is by far the easiest challenge so it should be a cakewalk. Just don't let go of the gas and use circle/drifting as your way to brake. Get Gold on the time sub-challenge and Bronze on the rest (but you'll probably get at least Silver because they're simple and can be cheesed if necesesary) and you'll easily get over 100k. For the Nitrous sub-challenge, only boost on straightaways until you get to the end and you can boost in circles to get to 60 seconds. Be mindful of the gas gauge as that's the only way you can "fail" this challenge because you need to finish to get 100k. Use the Snake and Tire Rings to make sure your bike doesn't break.
