The Facts Flash on Instagram: "On the final leg of the women’s 4×100 relay, the world watched something special. The 100m world champion, Sha’Carri Richardson, chasing down the 200m world champion, Shericka Jackson. Pure speed vs strength at top-end velocity. Two individual champions. One baton. One finish line. This is why relay races are never predictable — and why championships are won in the last 100 meters. #olympics #shacarririchardson #sherickajackson #amazing"
