For the javelin even you hold down fire to build up speed, and push left to throw the javelin, holding it left before releasing to change the angle. In the equestrian event, you must use up to increase speed, and fire or right to jump when appropriate to clear the hazards - too many faults will see you disqualified.
Fencing involves moving your foil using the joystick, always staying one step ahead of your opponent, retreating when appropriate. The kayaking event involves navigating a river by controlling the direction, ensuring that all the gates are past correctly even when this requires some precise lining up. You can also load the events from Summer Games 1 in, to play all 16 events in a marathon session.
