Ridiculous Triathlon is an endless runner in which players compete in an exciting three-stage race: race, cycling and swimming. The players simultaneously control a team of three characters that run through the iconic streets of Barcelona, London and Tokyo.

Each stage of the triathlon has its own dynamics and unique controls, such as stacking the characters one on top of the other to avoid obstacles during the race, use the accelerometer to control the bicycle or, finally, slide your finger across the screen in order to make that the characters swim from side to side, jump or dive under the obstacles.
