Sprint legend Michael Johnson believes Usain Bolt should consider moving up to 400m after an impressive relay display. Bolt clocked a 43.58-second split in a 4×400 relay at a local meet in Jamaica 10 days ago.  American Johnson’s world record from a standing start is 43.18 sec and his best split time in a relay – from a rolling start – was 42.94.  “He has the ability to be a world record holder. If it were me, I would move to the 400 now,” said Johnson.  Bolt set world records for the 100m and 200m last year and was part of the Jamaica 4×100m relay team that set a world record and won Olympic gold in Beijing in 2008.

However, no athlete has ever held the world record in the 100, 200 and 400 metres.Last month, running the anchor leg for the Racers Lions team, Bolt collected the baton in fourth position, 20 metres behind the leader, and managed to close the gap to just 0.44 sec at the finish line. Johnson recently visited Bolt in Jamaica while filming for a forthcoming BBC Inside Sport documentary.
