Okay, it wasn't the normal 100m or 200m but the in-between distance of 150m and it wasn't done on a track. Instead, it was done on a street (Deansgate) in Manchester on a day when it's been throwing it down on and off all day, rendering the track that was laid down less than conducive for good sprint times I would have thought.
His time was 14.35 seconds, some 0.45 seconds quicker than the previous best by Pietro Mennea back in the 1980s; the last 100m was covered in 8.72 seconds. Needless to say, he won by a distance. Ominous form for all those racing him especially after it was only 3 weeks after his car crash which affected his training regime.
His 100m world record should be destroyed some time this summer by him given the right conditions (projection of 9.54 seconds is what I've seen).
