ABSTRACT:
A pace calculation device including an oscillator and a frequency divider used for timing purposes, an amplifier and a speaker for generating a signal sound, and a CPU for performing an operation. Times taken for a runner to run any first distance twice each at a different pace to the signal sound are measured. The CPU draws a relation between a pace and a run time on the basis of data on two different paces at each of which the runner run the first distance and data on the run times taken for the runner to run. A run time taken for the runner to run at any pace any second distance which the runner should run in a target run time is measured. The CPU calculates a pace at which the runner runs the second distance in the target run time on the basis of the relation, data on the pace at which the runner run the second distance, and the run time taken for that run. The speaker generates a signal sound on the basis of data on the pace calculated by the CPU.
