- The International Association of Athletics Federations has published a progression of road racing world bests and records that were widely recognized prior to ratification and official acceptance by the IAAF. According to that progression, Derek Clayton's 2:08:34 performance in Antwerp on 30 May 1969 was a world best at the time. Other road racing authorities, including the Association of Road Racing Statisticians, consider Clayton's performance to have occurred on a short course and recognize other athletes in the progression for world best in the marathon.
