I think i've won 1st place with that freeroll ticket like 4-5 times, much more times reached the final table.
At some point in that tourney you can simply let it go and don't bet/call, just sit and see what happens... that's how you win it.
This moment is when like 50 players remaining or when average stack is less than 3bb. It's better to sit and do nothing, that's how I won 1st place several times. You need to just fold everything... AA/JJ/AK = fold if it's not your BB.
Even at the big blind, let's say it's a final table 9 players left and average stack there is 3bb or less, you have AK or even KK at BB with 2.5bb stack and 3 players infront of you go all-in, one of them covers you, others will leave you with less than 1bb stack - what will you do? I will fold there.
And the starting part of that tourney is pure all-in rage, youneed to be lucky and play tight range.
