For the Top of the World (Bronze) trophy, I noticed the other day while my girlfriend was playing Skate 2, that one of the Best Trick challenges (Mountain Mayhem Street Contest #4) takes place at SV Peak during round 1. Upon realizing this I wondered if she could get the handplant early on in the career without finishing the deathraces. She was indeed able to, by skating down the ramp they start you at and hopping the hubba on the left, going between the bleachers and the wall to reach the halfpipe behind the spawn point. After that it was a simple matter of her building up enough speed to plant the lip before the "Return to Contest Area" warning did what it warned.
Just wanted to share that in case it makes it a little easier for anyone trying to get that trophy!
