I have two observations/comments: Was the track level? Isn't Bolt Tommy Smith two inches taller with muscle? Remember Tommy Smith ran 19.5h on dirt on a straight when he was in college. Always necessary to have a historical context.
The 150m dissected – splits and projections
Bolt's running is anything but lead-footed. He ran the first 100m in 9.90 seconds, which is an extra-ordinary time and a sign of things to come. But even more amazing, the final 100m (from 50m to the finish line) were clocked in an astonishing 8.72 seconds! That is being reported, though it's so fast I'm almost sceptical. The splits, as recorded during the race, were:
- 50m – 5.64s (this compares to 5.50s in Beijing, by the way)
- 100m – 9.90s (a split of 4.26 s. In Beijing last year, Bolt's last 50m of his 100m was 4.19s, including the infamous celebrations)
- 150 – 14.35s (split of 4.45 s)
