Achieve a podium finish in the Winter X Games Tournament

The Winter X Games are the last event of season 3. There are 3 events you need to complete to get this, the first two to unlock the final and then the final itself (you can leave the DC challenge for now if you want although it does have a trophy associated with it also, see "Cool Running" and the platinum medal will be needed in that challenge for "Platinum Performance"). Again the difficulty can be dropped if you are having trouble and for this trophy you just need to be in the top 3 finishers of the final event but it will need to be won eventually for "Into the DiRT"
