What would Jerome Drayton’s marathon time be with today’s shoe technology?

Based on the effect the top carbon-plated shoes have on performance, Drayton's record would still stand

At Japan’s Fukuoka Marathon in 1975, Canada’s Jerome Drayton smashed his Canadian record from 1969 to win the marathon in 2:10:09 – a record that stood for 43 years until Cam Levins broke it at the 2018 Toronto Waterfront Marathon (2:09:25). When Levins set the record, he ran in the Hoka Carbon Rocket X, a shoe with carbon-plated technology Drayton did not have 43 years prior. Both times are remarkable, but it brings into question what Drayton’s time would translate to today if he had had carbon-plated shoes.

In the 70s, the Fukuoka Marathon had the reputation as the unofficial world championship, as organizers would invite the best marathoners from around the world to Fukuoka to compete. Drayton won the race three times in seven years, beating the likes of marathon greats American Frank Shorter and Japan’s Shigeru So (who held the world record from 1978 to 1980).

When Drayton set his record he wasn’t wearing the Adidas Adizero Pro or Nike Vaporfly. He had the Adidas SL76 on his feet, which was described as ‘the shoes for all seasons,’ built for pounding the roads in the marathon and jogging around the block. The shoe featured super-light technology, a ghillie loop lacing system and an EVA midsole – in short, a lightweight, flat running shoe.

In a 2021 video from Brigham Young University student Easton Allred, he discussed the development of carbon-plated shoes with a professor of biomechanics, Dr. Iain Hunter, who studies how people can run faster by the way they move. The two discussed whether carbon-plated shoes affect athletic performance and how much time they could take off each kilometre.

Hunter found that the top carbon plated shoes can take off two to three seconds per kilometre.

If you take Drayton’s time of 2:10:09 and take two seconds off each kilometre, it correlates to approximately 84 seconds off his time (2:08:45). Again, this calculation is hypothetical, but that time would be a record and untouched by any Canadian runner to this day.
