Secret room in Lara's:
House push the switch behind the Diving board.Then go to the main room where the stair cases are.Go to the newly open door and flip the switch and do a reverse roll and dash to the other side of the room and do a running roll.You must be calm and keep trying. It took me 10 trys but i finally mastered it but anyways when you enter the room you see a fire place and 4 podiums 2 of them have the artfacts of the other 2 adventures of Lara Croft. When you leave just push the button 2 times and the door opens

Hidden Path in Lara's Race Track:
In the race track when you go down in the underground tunnel and go over the jumps at the wall to the left you will see a climb that is really steep and if you drive up it and it takes you to a small room and then drive out the opening. When you go through just go strait and the short cut takes about 5 seconds off the timer
