A method for timing races and apparatus for performing the method including a cinematographic camera the lens of which is directed onto the finishing line. All data necessary for the evaluation of a race from preparation for start, start and finish appear on a single document which may be a photographic film or a magnetic tape. On such record will be shown the starting signal (37), the reaction times (t2, t3) of the participants of the starting signal, possibly the wind speed during the race and finally the arrival times (t6, t7) of the participants. The several parameters are recorded together with a scale giving reference times. |
