@sifanhassan runs the 2nd fastest marathon of all time 2:13:44 after attacking the World record during the early stages of the Chicago marathon. Hassan surely has to be the greatest runner of all time, throughout her career she has been world class at all distances from 800m all the way to the marathon. And ran a 3:55 1500m only 2 months ago!?!?! 📸 @globalsportscommunication
