Crazy Athletics - Summer Sports & Games (EP)

Only two keyboard buttons (if you are playing this on PC) are needed: S and Z. The tricky part is to find the right time to hit the S button to start running. My advice is look only at the circles as they come; pay attention to nothing else. When they appear to be lining up with the circle that bears the letter, press the key. Pressing it long before results in a DQ. After hitting the S key, pay attention to the circles as they come for the Z key. You do not have to be prefect but try not to hit the key too early or else you will hit the bar as you jump.

You can practice the Z patterns in the training section of the menu. At the events' page, press the Esc button (or Start button on your game controller) to load the small menu and click on the treadmill icon. Here, you select Technique 1 and practice your patterns. Once you find that rhythm, do the event and you should get this achievement in no time.
