Second-fastest man ever after Bolt! Why Jacobs’ sprint won’t enter record books

Olympic champion Marcell Jacobs blazed to a 9.67-second 100m at the Austrian Open, a time second only to Usain Bolt’s world record. However, a strong tailwind of +4.1m/s means this incredible feat won’t be officially recognised. Despite the wind, Jacobs’ performance signals a strong comeback, placing him among the fastest wind-assisted runners ever.
