1 year later hes the fastest 100m sprinter of all time, on his 5th attermpt. He moves his 200m pb up from 19.93 to 19.3. People struggle to move their 200m pbs up by 0.05.
Meanwhile Bolt in a year has moved his up a massive, massive 0.6.
And never forget that every other person to come before this geneation of world records was also a talent and was doped to the gills. Only Maurice Green hasnt been caught yet. Lewis doped. Gatlin doped. Montgomery doped. Ben Johnson doped. And in a sport where people struggle for improvements of 0.01, up comes Bolt, breaks that by 0.1
.......
The other guys made minor improvements slowly over the years on the mens 100m record.
Put it like this.
It took 16 years to get the world record from 9.93- 9.79. It took Bolt 2 years to get the world record down from 9.73 - 9.59
I haven't quoted everything.
First of all the progression of the world record. Long periods were the record barely changes, if at all are common to all of the shorter distances and jumps in track and field.
200m Pietro Menna (WR lasted 17 years) Michael Johnson (12 years)
400m Lee Evans (20 years)
800m Seb Coe (16 years)
110m Hurdles Colin Jackson (13 years)
400m Hurdles Kevin Young (18 years and counting)
Long Jump Bob Beamon (23 years), Mike Powell (19 years and counting)
Triple Jump Jonathon Edwards (15 years and counting)
High Jump Javier Sotomayor (17 years and counting)
Pole vault Sergei Bubka (16 years and counting)
These records were set at various times from 1968-1996 and withstood advances in doping technology, with the absence of a 'killer' drug, like EPO.
World records in these events generally aren't set in steady progressive increments. They make sporadic big leaps forward.
As to Bolt. In 2007 he was considered to be underachieving. Partly due to injuries and partly due to preferring partying over training. No drugs can make the improvement from 2007-8. If they could, others would be taking them.
If Bolt's improvements are to be attributed to drugs, why are there no other athletes making these huge leaps forward? You can count on one hand the runners who have gone faster than Ben Johnson did in the 80s.
Sportsmen aren't machines. They don't operate exactly the same way every time. There have been many other examples of vast improvement in sport: Alastair Cook, Gareth Bale, Goran Ivanisevic, Lee Westwood, to name just a few.
The biggest factor is usually mental. It's a vastly underrated variable aspect of sport. I know from personal experience. As a teenage hurdler and sprinter, I went from being the reserve hurdler for the school team to running at the English Schools finals in the space of seven weeks. Physically there was no change in me at all. It was completely mental.
