Abstract: An electronic timepiece includes a display unit, an altitude measurement unit that measures an altitude, a RAM that stores an ascent integrated altitude plan value which is a plan value of an ascent integrated altitude value, and a CPU that calculates the ascent integrated altitude value obtained by integrating an altitude variation amount during an ascent, based on an altitude measured by the altitude measurement unit, that calculates an ascent achievement ratio which is an achievement ratio of the ascent integrated altitude value with respect to the ascent integrated altitude plan value, and that causes the display unit to display the ascent achievement ratio.

Abstract: To measure a walking pitch or a running pitch more accurately with a simpler structure. Acceleration sensors detect accelerations and output acceleration signals corresponding to the accelerations. A CPU detects a cycle in which a user touches the ground at the time of walking or running based on the acceleration signal and calculating a first pitch based on the cycle of touching the ground. The CPU also detects a cycle in which the user swings his/her arms based on the acceleration signal and calculates a second pitch based on the cycle of swinging arms. The CPU determines either one of the first pitch and the second pitch which satisfies a given condition as a walking or running pitch of the user.
