Van Niekerk shatters world record in 400 to win Olympic gold (Yahoo Sports)

Exploding out of the blocks in lane eight, Wayde van Niekerk didn’t see another runner during the entire Olympic 400-meter final. The South African sprinter broke Michael Johnson’s 17-year-old world record on Sunday night in Rio de Janeiro, leaving two of the greatest one-lap runners of this era in his dust. Van Niekerk finished in 43.03 seconds – 0.15 seconds faster than Johnson ran on Aug. 26, 1999 in Seville, Spain.
