The silver medals are everywhere. On the first level when you go through the mirror you will end up at the the beach. When you jump on and off the big rocks and you land on the building do not grind down the rail. Look round and you will find a silver medal. After that go down the rail and when you go through the loops you will be running on water. To the left there will be another silver medal and a life (1up). Be warned because if you walk on a rock you cannot run back off it.
