How to unlock the Heart Of Gold achievement in SSX - Definitive Guide
While this can be done on any run, I would recommend Mount Robson in the Rockies. Furthermore, it would be good practice if you already had:
A gold medal on Mount Robson is two complete runs down the mountain, followed by a small fraction of a third run. As mentioned above, if you can make it down once without armor, managing it twice with armor is much more doable. Take it carefully, there's no need for Tricky or boosting since your biggest enemy is the trees.
Starting on your second run, the lower half of the mountain gets covered in snow and it's difficult to see. Stay calm, and remember that when it happens, you're likely about to run into a pattern of three fallen trees to quickly jump over.
EDIT: From Calex dEUS, using a low level board helps, as it goes slower; some runs, going faster will simply ruin you. Additionally, using the button to jump as opposed to the right stick is easier.
2nd try I picked the worst board I had and did it with ease as it was much slower :D
If you have played through World Tour you likely have an idea of which Survive event you found the easiest, however the option to Survive It! can be unlocked on runs other than where the original Deadly Descent was held. I would recommend staying away from Antarctic and Himalayan survival events, as no matter what there is a solid limit to how far down you can go, as your Oxygen reserves will eventually deplete in the Himalayas, and no matter how good you are, touching shadows and having your core temperature lowered is unavoidable in Antarctica.
I would recommend any survival event requiring armor, as I found those the easiest if you simply avoid the obstacles, but note that for each run you complete, you will take extra damage from hazards. Distances differ, but usually no more than two full runs of a survival course are required for a gold medal.
