A gait monitor 100 is disclosed which has a pair of movement sensors 501, 503 configured to be placed on either side of a user's head, preferably secured in the ears. Therefore, the movement sensors 501, 503 are each placed on both sides of the user's body but in equal distance to the midsagittal plane of the user and can monitor the gait of the user without need of any movement sensor centrally aligned in the midsagittal plane. Furthermore, the gait monitor 100 is able to determine if the steps of the user strikes the ground in a heel strike or forefoot strike in order to help the user improve his running efficiency.
