There are some events in sport which remain unforgettable. ISTAF on August 22, 1975 is among them. In pouring rain Steve Williams of the USA equalled the world record for the 100m with 9.9 seconds – hand timed since electronic timing had yet to be introduced. It was much the same for Guy Drut of France who delivered a thrilling duel with the American Charles Foster in the 110m hurdles. All three watches of the track officials as well as the back-up watch shown to the 20,000 spectators recorded 13.0 seconds, hand timed, also a world record.
