Completely mind blowing, 2 human beings under 2 hours in one race: PV Sindhu on London Marathon

Two-time Olympic medal-winning shuttler PV Sindhu penned a note after Sebastian Sawe and Yomif Kejelcha completed London Marathon under two hours. "For decades...sub-2 hour marathon felt almost impossible...Today Sawe ran 1:59:30....Ceiling of human endurance just moved," she wrote, adding, "Somehow it gets crazier. Kejelcha ran 1:59:41 in his debut. Two human beings under two hours in one race."
